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

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.[1] 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. Conductive polymer blend.[2][3] Impact of small electric and magnetic fields on the polymer was studied.[4]
• Application: PEDOT:PSS and poly(9-vinylcarbazole) (PVK) can be cross-linked to form a multi-layered organic light emitting diodes.[8] Proton exchange membranes such as Nafion 212 can be coated layer by layer with PEDOT:PSS and poly(allylamine hydrochloride) (PAH).[9]
• Features and Benefits: Reduced mean particle size with a tighter distribution of sizes allows for the creation of a smooth surface on the ITO electrode, and so electric "shorts" in LED devices can be reduced. Greatly reduced inherent conductivity reduces the occurrence of "cross-talk" in very small pixel (less than 10 micron) matrix array displays.
• Packaging: Packaged in poly bottles
