Poly(3, 4-ethylenedioxythiophene): Conductive coatings, technical applications and properties



Poly(3, 4-ethylenedioxythiophene) (PEDT) is a new polymeric organic conductor which, when combined with polystyrene sulphonic acid, produces a system that can be processed as an aqueous solution and yields effective antistatic coatings for films. The antistatic effect is achieved with coating weights of just a few mg PEDT/m2, resulting in films with a surface resistivity of 106 ω/□.
