Description

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 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 (CP) 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 is a low cost CP that is produced with physical appearance (for example dispersible pellets). The following are the properties that make PEDOT:PSS a viable polymer in organic electronics:

• good optical properties
• high conductivity
• functionalization of nanomaterials
• high thermal stability
• easy processing

Application

Orgacon DRY is specifically useful for water sensitive formulations containing UV curable monomer (suitable with small amount of water) and pre-polymer based formulations.

Orgacon DRY pellets can be re-dispersed in organic solvents such as ethanol. The resulting dispersion can be used in coating - or ink - formulations targeted for different applications.

Allow retention of PEDOT/PSS key properties in polar organic solvents; such as Ethanol; Surface Resistance: 200~450 Ohm/square; Visual Light Transmission: ~85%

PEDOT:PSS can be used as a conductive material with a high mobility for charge carriers. It can be used for a wide range of energy based applications such as organic printable electronics, textile electronics, electrochemical storage and supercapacitors, and lithium ion batteries.

Virtually 100% absorption from 900-2,000 nm. No absorption maximum from 400-800 nm. Conductive polymer blend.
