Coating composition comprising aniline terminated waterborne polyurethane and poly(3,4-ethylenedioxythiophene)/polystyrene sulfonate

摘要

PURPOSE: A coating composition has excellent antistatic performance and electric conductivity and forms a coating film with extremely low surface resistance. CONSTITUTION: A coating composition contains an aniline terminal-containing water-dispersible polyurethane and poly-3,4-ethylene dioxythiophene/polystyrenesulfonate. The mixing ratio of the aniline terminal-containing water-dispersible polyurethane and the poly-3,4-ethylene dioxythiophene/polystyrenesulfonate is 1:0.1-0.3 (w:w). The poly-3,4-ethylene dioxythiophene/polystyrenesulfonate is a conductive polymer doped with the poly-3,4-ethylene dioxythiophene/polystyrenesulfonate.
