General description

High-conductivity grade.
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. It is mainly used in organic electronics due to the properties, which include
  • low band gap
  • good optical properties
  • high conductivity
  • low redox potential
  • easy processing
  • tunable film forming ability

We are committed to bringing you Greener Alternative Products, which adhere to one or more of the 12 Principles of Green Chemistry. This product is used in energy conversion and storage, thus has been enhanced for energy efficiency. Click here for more information.

Application

Orgacon S315 is ready-to-use and made with conductive polymer PEDOT:PSS. Typical application processes are slot die, Meyer bar and gravure coating. It is particularly designed for optimal properties on PET and meet the requirements of several transparent electrodes applications as alternative to ITO.

  • ITO substitution coating.
  • ITO-free OPV.

  • Surface electrical resistance (SER) at 90% VLT* (visual light transmission): 125 Ω/square.
*Typical properties on PET with bar coater. Thermal cured at 130 °C/ 6 min. VLT according to ASTM D 1003, excludes substrate.
  • Stability ratio R/R_0 (500 hr at 60 °C, 95% RH) : 1.3.
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), dye sensitized solar cells (DSSCs), organic light emitting diodes (OLEDs), supercapacitors and biomedical sensors.
PEDOT:PSS is widely used as a transparent and conductive coating in applications like touchscreens, flat panel displays, and photovoltaic devices. It is commonly used as an electrode material in OPVs. It serves as the hole transport layer and a transparent anode, enabling efficient charge extraction and transport within the device.

Preparation Note

  • Dilute with DI water or compatible solvent if needed.
  • Pre-treated substrate with corona- or plasma treatment increase adhesion.

Other Notes

  • These additives have low water content (less than 100 ppm).
  • Please handle under inert and moisture free environment (glove box).
  • Keep containers tightly closed.
  • Keep away from heat and ignition sources.
  • Store in a cool and dry place.
  • Avoid storing together with oxidizers.
