General description

Aqueous surfactant-free dispersion of PEDOT:PSS neutralized to pH >5. Suitable for preparation of pH-neutral transparent conductive films printed electronics applications (e.g. hole injection layers). 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.
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. PEDOT:PSS is majorly used in organic electronics due to the properties such as:
  • low band gap
  • good optical properties
  • high conductivity
  • low redox potential
  • easy processing
  • tunable film forming ability

We are committed to bringing you Greener Alternative Products, which adhere to one or more of the 12 Principles of Green Chemistry. This product is used in energy conversion and storage, thus has been enhanced for energy efficiency. Click here for more information.

Application

PEDOT:PSS can be used as an electrode material that forms a layered structure with a high mobility for charge carriers. It can be used for a wide range of energy based applications, such as organic photovoltaics (OPVs), dye sensitized solar cells (DSSCs), organic light emitting diodes (OLEDs) and supercapacitors.
Virtually 100% absorption from 900-2,000 nm. No absorption maximum from 400-800 nm. Conductive polymer blend.
