Abstract: PURPOSE:To obtain the title material of a uniform film thickness with excellent film forming property, by markedly decreasing the formation of benzidine, etc., by performing electrolytic polymerization in a state in which gases generation the counter electrode is prevented from arriving at the working electrode by isolating the working electrode in the electrolytic polymerization solution. CONSTITUTION:A working electrode and a counter electrode are set in an electrolytic cell for holding an electrolytic polymerization solution so that the distance between the electrodes is not necessarily large, and moreover they are constituted so that gases generated in the counter electrode in, for example, a vacuum atmosphere is forcibly removed by upwardly passing gases without diffusion in the horizontal and downward directions, whereby the electrodes are brought into a state in which the gases generated in the counter electrode are prevented from arriving at the working electrode. For example, an electrolytic polymerization solution comprising a feed monomer (e.g., aniline) for an organic polymeric material such as polythiophene, polyaniline or poly-p-phenylene, borofluoric acid and ion-exchanged water is fed to said electrolytic cell and the pressure in the cell is decreased to a vacuum of 600-750mmHg with, for example, a vacuum pump to electrolytically polymerize the solution at -40-30 deg.C and a current density in the working electrode , thus producing the title material comprising a high-quality organic polymeric film on the working electrode.

Abstract: PURPOSE:To obtain polyaniline with wide range of electrochemical activity, suitable for electrode material for fuel cell, optical conversion device, biosensor, etc., by modification of original polyaniline with an enzyme. CONSTITUTION:The objective polyaniline can be obtained by modification of original polyaniline (pref. prepared by reduction and/or alcohol treatment of a polyaniline made by electrolytic polymerization) with an enzyme (e.g. gluoxidase). Said modification is preferably such that 1.0X10 -6.6X10 units of an enzyme (per g of the original polyaniline) is immobilized by clathration.

Abstract: PURPOSE:To provide the titled polymer having fibrous structure, large in electrical discharge capacity when used as electrode materials for cells, photocells, etc., contributive to extention of the working life of the electrode materials. CONSTITUTION:For example, aniline is subjected to electrolytic oxidation using an electrolytic polymerization liquid comprising borofluoric acid. The resulting polyaniline is then subjected to reduction or alcohol treatment to obtain the objective polymer having fibrous structure. The fiber diameter is pref.

Abstract: PURPOSE:To obtain polyaniline having a large discharge capacity and being useful as an electrode material for cells, photocells, etc., by subjecting polyaniline to reduction treatment and/or alcohol treatment. CONSTITUTION:Polyaniline obtained by, e.g., an electrolytic polymerization process is subjected to electrolytic reduction treatment for 3-2,500min at a current density of 0.1-80mA/cm , and then subjected to chemical reduction by immersing in a 5-20wt% aqueous hydrazine solution for 10-1,500min or is subjected to alcohol treatment by immersing in a 30wt% or higher solution of an alcohol such as methanol for 5min-24hr at 10-40 deg.C.
