After re-reading my peer review of your outline, I can see that most of all my comments and concerns were adequately addressed. I appreciate that you added a kinetics part and wrote "Glow Discharge Polymerization" as a same meaning. But, I suggest you compare Atmospheric-pressure plasma as a conventional plasma polymerization.
- Your web page is suitable for first-time/general users as well as for those looking to understand the topic in more detail. Also each sections are logically flowed and have proper length without over-emphasis or under-emphasis.
- Sandbox quite well satisfies the objectives listed in your outline. Most of the important terms are linked to their Wikipedia pages, but there are some words necessary to link. --> printing, bifocals, hydrophobic
- You should change chemical structure of acrylonitrile and enlarge Figure 4. Other images are aligned appropriately with the text.
- The references are complete and inclusive of textbooks and journals.
- Your website satisfies all the assigned criteria (a minimum of 3 sections, 3 figures, 8 references)
- Your overall presentation is good and easy-to-read. But, I found some typos as follows.
- at Types of reactors, "This uses an RF coil rapped around" --> This uses an RF coil wrapped around
- at Monomer section, "Plasma polymers can be though of" --> Plasma polymers can be thought of
- at General Characteristics of Plasma Polymers section, "These properties are due to the large about of" --> These properties are due to the large amount of
- at General Characteristics of Plasma Polymers section, "The permeabilities of plasma polymers also differs" --> The permeabilities of plasma polymers also differ
- at Applications section, "with a flux of 6.4 gallons/ft2 a day" --> with a flux of 6.4 gallons/ft2 a day
- at Applications section, "Plasma polymers form from tetramethoxysilane" --> Plasma polymers formed from tetramethoxysilane
- Your web page is well-constructed and very helpful both to general user and one who want to know in more detail. You did a great job describing from background of plasma polymerization to applications. You showed very proper images on each sections and referred a closely related references. I believe that you created one of the well-ordered and valuable Wikipedia page. The only thing you should pay attention to is to fix some typos and add more links to Wikipedia.

- I think you have a good start on the appropriate topics that need to be outlined in the Plasma Polymerization page
- I think it is definitely important to talk about the applications that these polymers have however, you might want to only address a few applications because otherwise the amount of information that you have to add for each of the subtopics (i.e. molecular wires, polymer LEDs, and magnetic ceramics) may become overwhelming and detract from the plasma polymerization process
- Introduction and background seems like a good place to start, the other thing might be to talk about the scientist that pioneered this process
- What was the original use of the plasma polymerization process
- Basic Operating Mechanism
- A picture I feel would make this section really easy to understand
- A brief introduction and explanation of how the plasma is actually created
might be helpful as well, this might help give a general background that might help better establish the context of the project
- I think the types of glow discharges is definitely a GREAT thing to talk about
- The picture is really good, there is nothing I can really say about it. It outlines the synthesis route well and it is good size and quality. The larger resolution size of the picture is also good quality which is important
- maybe talk about what exactly makes the complexity of the chemical reactions “complex” in regards to other radical polymerizations
- I definitely do not know what the various i, j and k radicals are for the various radical monomers (which is represented by M?) so that would definitely be something to note in the actual figure or in the caption
- What allows for a monomer to be suitable for ionization processes in the plasma state? Are large monomers not stable for the ionization process in the plasma state? What specifically makes the double bond important for the polymerization process?
- It might also be helpful to talk about more complex effects in the ionization process for example, do chlorinated products undergo ionization better than brominated products?
- Is there a substantial difference in rate for ionization species depending of individual substituents (Cl, Br, I) in a monomer?
- General Characteristics of Plasma Polymers
- I feel like the general characteristics of plasma polymers is something that should be outlined earlier in the page
- This information seems less detailed than some of the above information and processes
- For example, if you talk about free radicals in plasma polymers you do not have to talk about it again in synthetic routes, you can simply refer to it again
- Also, I think explaining the internal stresses that arise in plasma polymers would start the basis for what makes a good polymer and a good monomer for plasma ionization/polymerization
- The radical initiating groups of the monomers would also be outlined in this section which would be good to know before you get into the process
- Furthermore, you could outline common plasma polymers and composites that are hydrocarbon, fluoro(chloro) carbon, nitrogen containing which you could then expand upon in your monomer selection section
- Advantages and Disadvantages of Plasma Polymerization
- Are there specific advantages such as various electrodes that could be used or is the process enslaved to such things as only being able to inert metals for the electrodes?
- Be sure to explain what makes a clean polymerization
- How is polymer length effectively controlled in comparison to traditional methods for controlling polymer length?
- Is there a specific component which makes the technology expensive, the monomers or the overall instrumentation?
- What is vacuum technology?
- The picture of the various monomers probably needs to be arranged differently so that it does not expand into the reference section
- I think the applications are definitely good ones to focus on, these applications are all great technologies that are up-an-coming and not simply outdated
- I like the number of references you have and I think it is really good that you have a good mix of book AND journal sources for your site
- Overall, I think your site it off to a really good start! You definitely have a good basis to start with. There are a lot questions that I have in regards to things you are going to talk about in your final site. However, after a little searching on Wikipedia, I think you could substantially minimize the amount of work that you would have to do by adding links to specific topics so that you do not have to take up space outlining and defining these topics on your own page. I also think that your outline is a great way to lay out the topic as well as the details of it. The questions that I asked are most likely things that you will end up expanding in your final site however, I simply noted them since they are inevitably topics you will have to talk about. As an outsider, it is probably easier for me to spot questions people will have since their knowledge level of the subject will be the same as mine if not, less. All in all, great start to the topic of plasma polymerization.

- I think your objectives are original, clear and appropriate for Wikipedia. Since current site is not informative at all, you can modify enough and contribute quite well. You should arrange well because you will cover a bunch of things. Be careful not being too lengthy and use link function properly.
- I think introduction part is most important. So you should explain enough by using correct terminology and remove ambisuous things for people not to be confused.
- People can often call plasma polymerization as a glow discharge polymerization, so you would better mention about two terms. You already know, but I want to recall.
- Plasma polymerization refers to the formation of polymeric material, by using either the plasma state of monomer or reactive species created in the plasma state. You can compare these two categories.
- Also there is possible that plasma treatment is confused with plasma polymerization. You will explain the differences between those such as concepts, apparatus and reaction conditions.
- Basic Operating Mechanism
- I believe you will add a beautiful picture for apparatus.
- What about adding "kinetics" part? I found a paper about rate and mechanism for plasma polymerization. "Glow discharge polymerization-rates and mechanisms of polymer formation, european polymer journal, 1971, 7, 363"
- I have heard plasma treatment can be done under ambient pressure. If plasma polymerization can be conducted as well, to add that is beneficial.
- You would better upload synthetic images having better picture quality.
- This part is also very important if people can easily introduce plasma polymerizarion method. You should mention criteria of monomers which are used for that.
- General Characteristics of Plasma Polymers
- I think you will add proper references for each properties.
- Advantages and Disadvantages of Plasma Polymerization
- How about changing the part title to "Advantages and Disadvantages".
- You should check mass production of plasma polymerization is easy or not. I think mass production is difficult due to high set-up cost for vacuum. So, plasma polymerization under ambient condition is promising.
- Biomedical application "Biomedical applications of plasma polymerization and plasma treatment of polymer surfaces, Biomaterials, 1982, 3, 68.
- Sensor devices "Thin-Film Glucose Biosensor Based on Plasma-Polymerized Film: Simple Design for Mass Production, Anal. Chem., 2000, 72, 2671"
- Do you feel that current images are not good? I believe you will add great images having high resolution.
- An image for monomer structure is not located in proper place.
- I recommend that you draw schematic mechanism by using Chemdraw.
- I think you chose appropriate papers and books. However, please refer some papers I found.
- This is helpful to you. "Glow discharge polymerization, J of Poly. Sci. Macromolecular Reviews, 1981, 16, 199"
- You can find more great papers if you input "glow discharge polymerization".
- You made a great outline and I believe you will complete a beautiful page. You almost create new page because current page for plasma polymerization has little information. You can link some pages to explain terminology more effectively since this page is somewhat long.

- In the first paragraph, maybe keep measurements in the same class, instead of go from angstroms to microns
- I like the basic background here, it provides a nice transition into the “hard chemistry”
- be sure on the final site to change the heading here to either introduction or background
- Is the [Goodman] here a place holder for a future reference?
- Maybe list some of the various monomers that could be used to polymerize
- I like the figures that are provided but this is a very dense section and I feel similar figures might be helpful in clearing up some of the confusion
- What source are the free electrons being made from? Is it the gas or is it the monomer that is having free electrons being formed?
- Are there disadvantages to using “low-temperature plasma”?
- Does the plasma causes initiation of anionic or radical species to be created?
- Make sure all references to pictures are designated by “figure #” instead of using non-descript indicators like picture on the right
- For the monomer gas, can you only use gaseous monomers or do they need to be vaporized?
- Are there advantages to using a continuous flow reactor or is this method outdated? Here, it only sounds like bad things occur from this method
- in electrodeless section, type “which sends uses”
- I’m a little confused to what non-equilibrium plasmas are or is
- You make a reference to ethane being faster but you said that vinyls are usually used, did you mean ethylene?
- The input power section is confusing, it is stated that increasing the frequency up to 5kHz increases rate and then inhibition happens but then you say a second maximum in frequency occurs at 6MHz?
- As the pressure decreases, do polymers become less uniform?
- If there can be a double radical on M, does it actually attach to the metal and polymerization propagates off one end attached to the metal?
- Are the monomers/polymers covalently or electrostatically attracted to an electrode?
- I feel like the last sentence should be your opening sentence to the synthesis section
- Is there some sort of general mass cutoff to monomers used for plasma polymerization?
- Is there some idea as to why compounds with oxygen, halides, aliphatic hydrocarbons and cyclic hydrocarbons decomposed more readily?
- What is main contributing factor to decreasing rate of polymerization?
- spelling error-“due to the large about of…”
- overall I think this section is very strong, it is well explained and easily understood
- What do you mean by pinhole free?
- I have been getting the impression that this process is pretty difficult to control but it is stated that the thickness of the coating can be easily varied, how is this possible?
- It also seems any sort of contamination can have serious effects on the polymer, such as incomplete vacuum or monomers that are not EXTREMELY high purity
- I think this section is well though out and is significantly expanded
- Not only are the applications numerous but they are also “real” in the sense that several people would benefit from their applications
- I think it might be good to talk about some of the issue that exist which are trying to be fixed in order to expand the process to more applications
Overall, I think the site is well planned and executed. I feel with a few tweaks that the site will be a tremendous addition to Wikipedia. The field of polymerization will benefit greatly from your layout of plasma polymerization. Definitely, be sure to read through your site in entirety to be sure that there are no spelling errors. I look forward to seeing the final product!
