Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate)

Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) is a conductive polymer that is formed by electropolymerizing 3,4-ethylenedioxythiophene in a solution of poly(styrenesulfonate)(PSS). PEDOT is doped with positive ions and PSS with negative ions. It has the following properties that makes it a viable polymer in organic electronics:

• low band gap
• good optical properties
• high conductivity
• low redox potential
• easy processing
• tunable film forming ability

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 conductivity and 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.

PEDOT:PSS can be used as a high conductivity material with a high charge mobility. It can be used for a wide range of energy based applications such as photodetectors, organic photovoltaics (OPV), dye sensitized solar cells (DSSCs), organic light emitting diodes (OLEDs), supercapacitors and other biomedical sensors.
