PEDOT:PSS

Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) is an organic semiconductor wherein conjugated PEDOT is doped with sulfonated PSS, which acts as a counter ion. PEDOT is responsible for the conduction mechanism and the hydrated colloidal solution formed by PSS.
PEDOT:PSS has high electrical conductivity and good oxidation resistance, the properties which make it suitable for electromagnetic shielding and noise suppression. Thus, the polymeric film formed possesses high transparency throughout the visible light spectrum and even in near IR and near UV regions, displaying virtually 100% absorption from 900-2,000 nm. No absorption maximum from 400-800 nm was observed.

PEDOT:PSS acts as an intrinsically conductive polymer, which can be coated on a variety of substrates and nanoparticles like fullerenes (C₆₀) for the low-cost printing of electronics and optoelectronics based applications. Conductive hydrogels can be prepared by using PEDOT:PSS with polyethylene glycol-diacrylate, which can be potentially used in tissue engineering.
