Abstract

Interpenetrating networks (IPN) poly(acrylamide-aniline) polymer was synthesized by a two-steps aqueous polymerization method, which aniline monomer was absorbed in the network of polyacrylamide and followed by a polymerization reaction between aniline monomers. The poly(acrylamide-aniline) hydrogel possessed a conductivity of 25.28 mS cm−1. An interpenetrating network structure model with a three-dimensional network of polyacrylamide and a one-dimensional chain of polyaniline for poly(acrylamide-aniline) conducting hydrogel was proposed, and a conduction mechanism with charge carriers (protons) hopping along the polyaniline chain was suggested. The poly(acrylamide-aniline) hydrogels have predominant thermo-sensitivity. Poly(acrylamide-aniline) hydrogels possess loading and releasing properties, an anomalous release mechanism is found.
