Polyaniline cryogels: Soft and conducting
July 10-14, 2016
Polyaniline is important conducting polymer . It is prepared by the oxidation of aniline with ammonium peroxydisulfate in acidic aqueous media  (Fig. 1). When the oxidative polymerization of aniline is carried out in the presence of a water-soluble supporting polymer in frozen reaction media, in ice, a composite hydrogels are obtained after thawing. Such hydrogels are called cryogels and the prefix "cryo" refers to the way of their preparation.
