thread_title: A fluoropolymer base that is also a superacid

message: How is this stuff made?  Are relevant monomers known, e.g. CF2=CFSO3H and CF2=CF-CF2SO3H?  Is Nafion processable - soluble, spinnable, extrudable, etc.?  How is it coated onto electrodes etc?  How acidic is it?  --Smokefoot 04:46, 27 February 2006 (UTC)
replies: text: Well your professor blew it. The depicted functional group -O-CF2-SO3H is incorrect. And the picture in this article is pretty decent: it emphasizes that Nafion is related to triflic acid, with the key functionality featuring a highly acidic sulfonic acid group, an excellent H+ donor. Your probing questions are helpful for this project.--Smokefoot (talk) 01:21, 26 May 2008 (UTC)

thread_title: Additional information

message: I suppose that the following paragraph is essentially wrong:
"The greater the degree of hydration of the Nafion membrane, the lower the ion permittivity. Since water is a byproduct of the fuel cell process, this limits the utility for Nafion for PEM fuel cells." 
In the introduction of this paper http://www.springerlink.com/content/e451834817x482u3/fulltext.pdf?page=1, DOI 10.1007/s11708-007-0005-y, it's reported that water is essential to conduct protons. Cited: "Under water-swollen conditions, a Nafion membrane can conduct protons and block electrons."  —Preceding unsigned comment added by 130.83.232.68 (talk) 14:13, 24 March 2009 (UTC)

message: In properties, where it says " highly permeable to water." it should say "highly impermeable to water" or "waterproof".  — Preceding unsigned comment added by 200.104.249.103 (talk) 02:52, 10 August 2015 (UTC)

message: Hello fellow Wikipedians,
I have just added archive links to  on Nafion. Please take a moment to review my edit. You may add  after the link to keep me from modifying it, if I keep adding bad data, but formatting bugs should be reported instead. Alternatively, you can add  to keep me off the page altogether, but should be used as a last resort. I made the following changes:
*Attempted to fix sourcing for http://www.permapure.com/tech-notes/key-concepts/nafion-physical-and-chemical-properties/
When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at ).
