[edit] polymeration vs polymerization

From Google defnitions:

Polymeration is a reaction where monomers join together to form bigger macromolecules.

polymerization The composition of long chains of molecules called polymers from shorter chains called monomers,

I linked these words, maybe it's worthwhile to make stubs on them (I don't know yet if there are pages, I will se in 5 seconds...)?

[edit] Geffcken at ...

I'm trying to reconcile this edit, by an anon with no other edits, with the historical information that was already there. Where did Geffcken study or work? This is an earlier date than what was there previously, but I'm inclined to revert. Any ideas? I'm not even sure if 1939 is the earliest date. I seem to recall papers from early 1920s being cited, but I'll have to verify that. Ufwuct 22:00, 9 November 2006 (UTC)

This might contain the answers, but I don't have access to it right now. This article suggests that sol-gel processing occurred much earlier. However, I can't verify the sources to see what links these references have to sol-gels. Is anybody at a library at a large university right now who can access these articles? Thanks.

[edit] A form superior to teflon?

The first version of this article featured this: (...) as a means of producing very thin films of metal oxide for various purposes, including a form which is a superior alternative to teflon.

And now it is still there: (...)or as a means of producing very thin films of metal oxides for various purposes, including a form superior to teflon.

However, this is just nonsense, right? I mean, a thin film can be used for so many things, so why stress that a thin film can be used as a 'form superior to teflon'? This should be removed, it is too vague. It could be replaced with a comment that cites a property of a sol-gel fabricated polymer which is superior to Teflon, with an appropriate reference, of course.

[edit] Solid / Gel ??

Regarding the comment "The sol-gel process involves the transition of a system from a liquid (the colloidal “sol") into a solid (the "gel") phase."

I'm only guessing, but wouldn't the liquid phase be "gel", and the solid phase be "sol".

It lacks citations, it's completely biased toward the concept of sol-gel as a manufacturing technique but gives delightfully little actual information.

Sol=a stable dispersion of colloids/nanoparticles in liquid gel= a continous network of solid material with air or water in the "holes"

So the author has got it right, but he/she has missed that there has to be a drying for getting the solid material.) —Preceding unsigned comment added by 130.243.172.201 (talk) 18:21, 8 March 2008 (UTC)

[edit] Sol-gel vs. teflon

"including a form superior to teflon" has no meaning because:

  1. teflon is NOT a metal oxide and is NOT obtained by sol-gel
  2. superior as to what? mechanical properties, physicochemical properties...
  3. a reference should be included (journal article or book)

So I'm removing this part because it simply does not fit in the scope of the article.

[edit] Sol-gel properties

Second section (after Introduction):

  • Silicon alkoxides
  • Metal alkoxides: hydrolysis and condensation
  • Recent development by Kessler et al.
  • Metal chlorides

[edit] Requested move

Hello, I think "sol-gel" (with a dash) is more appropriate than "sol gel", therefore I suggest this page should be renamed "Sol-Gel". Also, he "sol-gel" page (with a dash) already exists, it is just a redirect to "sol gel"... so there should be no problem in renaming. Ste nohype 10:21, 19 September 2007 (UTC)

I've moved the page, per the request and the apparent commonness of the hyphenated spelling. -GTBacchus(talk) 22:47, 29 September 2007 (UTC)
