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 formed by electropolymerizing 3,4-ethylenedioxythiophene in a solution of poly(styrenesulfonate) (PSS). PEDOTs are doped with positive ions, while PSSs are doped with negative ions. The following are the properties that make PEDOT:PSS a viable polymer in organic electronics:
  • low band gap
  • good optical properties
  • high conductivity
  • low redox potential
  • easy processing
  • tunable film forming ability

Application

Screen Printing results on Autotype Autosta CT7 P77/55 screen with 300 mm/s
Curing temp. 130°C during 3 min
PEDOT:PSS can be used as an electrode material with a high mobility for charge carriers. It can be used for a wide range of energy based applications such as organic photovoltaics (OPV), dye sensitized solar cells (DSSCs), organic light emitting diodes (OLEDs), supercapacitors and other biomedical based sensors.
Screen-printable inks are based on conductive polymer PEDOT/PSS and enable patterning of transparent conductive structures from plain down to resolution of 100 microns on flexible and rigid substrates such as PET; PC; PMMA; PI; and glass. Screen-printing inks can achieve excellent characteristics such as flexibility and formability for electrodes of electroluminescent lamps; capacitive touch sensors; and membrane switches.
Virtually 100% absorption from 900-2,000 nm. No absorption maximum from 400-800 nm. Conductive polymer blend.
