Title:
PRODUCTION OF ELECTRICALLY CONDUCTIVE HIGH POLYMER MATERIAL
Document Type and Number:
Japanese Patent JPH0218423
Kind Code:
A
Abstract:
PURPOSE:To obtain the subject high-quality material, excellent in film-forming properties and having homogeneous weight and thickness distribution in a short time by controlling a current value in electrolytic polymerization versus time. CONSTITUTION:(A) A monomer for electrolytic polymerization, such as aniline or pyrrole, is dissolved in (B) an organic solvent, such as acetonitrile, and (D) a salt, such as LiBF4, is added to provide an electrolytic polymerization solution, which is then placed in an electrolytic cell. (E) A polymerization electrode (e.g. platinum) and a counter electrode (e.g. gold) are dipped therein to afford preferably 50muA/cm<2> to 3mA/cm<2> current density in the initial stage of the polymerization and then increase the current density at 0.1-1mA/cm<2> per sec. The above-mentioned monomer is finally reacted preferably at 10-120mA/cm<2> current density to afford the objective high polymer material.
