General description

Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) is an organic semiconductor prepared by doping cationic poly(3,4-ethylenedioxythiophene) and poly(4-styrenesulfonate) anion. Its high electrical conductivity and good oxidation resistance make it suitable for electromagnetic shielding and noise suppression. PEDOT:PSS based polymeric films have a high transparency throughout the visible light spectrum and even in near IR and near UV regions, with virtually 100% absorption from 900-2000 nm. PEDOT provides the conduction properties and PSS forms a hydrated colloidal solution.
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

Electrical conductivity measurements herewith reported were on a film deposited by spin-coating on a clean glass, then dried (130 °C for 15 minutes on a hotplate). The layer thickness was determined by scratching the layer and measuring the profile/height of the scratch by a stylus profilometer. Electrodes for the measurement were by evaporating metal contacts (four-point probes).
PEDOT:PSS is an intrinsically conductive polymer (ICP) that can be coated on various substrates and nanostructures like fullerenes (C60) to form composites with high electrochemical properties for applications like low-cost printed electronics, optoelectronics, and polymeric solar cells. It can be used as a conductive hydrogel with polyethylene glycol-diacrylate (PEG-DA) for potential applications in tissue engineering. PEDOT:PSS also finds use in other organic electronic applications like organic thin film transistors (OTFTs) and dye sensitized solar cells (DSSCs).
Ready-to-use high conductivity coating formulation.
Virtually 100% absorption from 900-2,000 nm. No absorption maximum from 400-800 nm. Conductive polymer blend.
