POLYTHIOPHENE-BASED CONDUCTIVE POLYMER SOLUTION COMPOSITION WITH GOOD CONDUCTIVITY AND TRANSPARENCY

摘要

PURPOSE: A composition is provided to produce conductive film which has good conductivity and transparency and used for shielding electromagnetic wave. CONSTITUTION: A PEDT is a conductive polymer which is water-soluble, stable against temperature and atmosphere and has good transparency while forming film. The PEDT 16 to 32 wt% is needed to have both good transparency and conductivity. Alcohol solvent used for the PEDT polymer is methanol, ethanol, propanol, isopropanol and butanol. The solution composition is to add sulfonate monomer dopant, alcohol solvent and amide-based organic solvent in turn in a minute while stirring PEDT solution in the blunger: and to mix it homogeneously.
