General description

Aqueous surfactant-free dispersion of high conductivity grade PEDOT:PSS polymer. Optimal performance in transparent conductive coatings may require addition of formulation ingredients (e.g. surfactants and high-boiling solvents).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 without a high boiling solvent (HBS), 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 make it a viable polymer in organic electronics.

Application

PEDOT:PSS can be used as an electrode material with high mobility for charge carriers. It can be used for a wide range of energy based applications such as organic photovoltaics (OPV), perovskite solar cells (DSSCs), organic light emitting diodes (OLEDs) and other biomedical sensors.
Used to prepare highly transparent conductive coating formulations. Primary and secondary nucleation by introducing PEDOT:PSS in a hydrogel was studied.
Virtually 100% absorption from 900-2,000 nm. No absorption maximum from 400-800 nm. Conductive polymer blend.

New Conducting and Semiconducting Polymers for Plastic Electronics

In the emerging field of organic printable electronics, such as OLEDs and organic photovoltaics (OPVs), there is a significant need for improved organic conducting and semiconducting materials. This paper reports our recent progress in two fields: 1) the development of solvent-based dispersions of the intrinsically conducting polymer (ICP) poly(3,4- ethylenedioxythiophene) (PEDOT) and 2) the synthesis of new electron-deficient (n-type) semiconducting polymers.
