Title: Conductive polymeric material and its production
Inventor: UDA HITOSHI
IPC: C08L5/08
Filed: 1991-02-04
Abstract: PURPOSE:To facilitate the formation of an easily processable and moldable conductive polymeric material having a functional group useful for fixing oxygen by oxidation-polymerizing pyrrole in a dilute organic acid containing chitosan and an oxidation polymerization agent and precipitating the polymer from an organic solvent. CONSTITUTION:Pyrrole is oxidation-polymerized in a dilute organic acid (e.g. formic acid or acetic acid) containing chitosan and an oxidation polymerization agent (e.g. ferric p-toluenesulfonate or hydrogen peroxide), and the formed polymer is precipitated from an organic solvent (e.g. acetone or ethyl alcohol). According to the above process, a water-soluble and easily moldable conductive polymeric material having a functional group useful for fixing oxygencan easily be obtained. Because an arbitrary conductivity can be uniformly imparted to this material, it can find wide applications such as a biosensor as a conductive oxygen fixation carrier. It can be stored for a long time when it is molded into granules.
