These proton exchange membranes usually contain an organic superacid. (A "superacid" has an acidity greater than that of 100% sulfuric acid.) Capehart et al of General Motors have developed a proton exchange fuel-cell membrane from a polymerizable organic superacid such as sulfonic acid, carboxylic acid, or phosphonic acid.
Cova-lent Si--C bond preserved the phase separation, and the absence of excess water prevented the solvatation of the superacid. One surprising trait on hybrids synthesized via cationic photopolymerization is that vinyl ether, known as the most reactive function, has been poorly explored so far.
These techniques are not ideal for fiber spinning because they damage the properties of the nanotubes, either by attaching small molecules to their surfaces or by shortening them.A few years ago, the Rice researchers discovered that chlorosulfonic acid, a "superacid," adds positive charges to the surface of the nanotubes without damaging them.

Olah obtained his first results by mixing hydrogen fluoride with antimony pentafluoride to produce a superacid so strong it could pluck atoms from hydrocarbon molecules, leaving behind an alkyl cation -- a molecule normally too unstable to be studied.
