General description

A conducting polymer such as poly(3,4-ethylenedioxythiophene) doped with poly(styrene sulfonate) anions (PEDOT/PSS) is widely used in various organic optoelectronic devices. PEDOT: PSS is a blend of cationic polythiopene derivative, doped with a polyanion. High electrical conductivityand good oxidation resistance of such polymers make it suitable for electromagnetic shielding and noise suppression. Thus, the polymer film was found to possess high transparency throughout the visible light spectrum and even into near IR and near UV regions, virtually 100% absorption from 900-2,000 nm. No absorption maximum from 400-800 nm. Impact of small electric and magnetic fields on the polymer was studied.

Application

Aqueous formulation of high conductivity grade PEDOT:PSS polymer dispersion suitable for transparent conductive coatings. Includes PEDOT:PSS and surfactants.
Used in ITO-free OPV applications as a highly conductive hole transport layer. Also can be used for optical films, touch pads, touch screen displays, flexible LCDs, and e-paper applications.
Virtually 100% absorption from 900-2,000 nm. No absorption maximum from 400-800 nm. Conductive polymer blend.
