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

Applications
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.
Features & 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.

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.

Applications
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).

Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) is an intrinsically conducting polymer (ICP) that is prepared by blending poly(3,4-ethylenedioxythiophene) (PEDOT) and sodium poly(styrenesulfonate) (PSS). It is an aqueous emulsion in which PEDOT is positively charged and the PSS is the counter ion (negatively charged). It can act as an anode or a cathode material based on the application. It can be spin-coated on different substrates at 1000-5000 rpm.
Preferably applied by spin-coating. Filtration of the dispersion through a 0.45 μm memberane filter is recommended before use. The coatings are dried at a maximum temperature of 200 °C for 1 minute, but a temperature between 50 °C and 150 °C is usually sufficient. The optimal thickness of the dried layer is in the range of 50-250 nm.
Applications
PEDOT:PSS and poly(9-vinylcarbazole) (PVK) can be cross-linked to form a multi-layered organic light emitting diodes. Proton exchange membranes such as Nafion 212 can be coated layer by layer with PEDOT:PSS and poly(allylamine hydrochloride) (PAH).[9]
Useful as an interfacial hole injection layer in OLED and PLED devices to lower operating voltages, increase luminescence efficiency, and enhance display lifetimes.
