Conductive hydrogels synthesized via chemical or physical crosslinking. (a) PEDOT hydrogel was synthesized via chemical crosslinking by free radical polymerizations.

(b) A single component hydrogel based on PCL–poly(ethylene glycol)–PCL grafted aniline tetramer copolymers via thermal gelation process.

The reversible sol−gel transition was observed by subsequent alternation addition of 1-adamantanamine hydrochloride (AA) and γCD2 into the mixture. Reprinted with permission from reference 108.
