一般描述

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.
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.

应用

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).

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. What is the ratio of PEDOT to PSS in Product 655201?

    According to our supplier, the ratio of PEDOT to PSS is proprierary information.

  4. How should Product 655201, PEDOT/PSS, be stored?

    We recommend that you store this product at 2-8°C, which is in accordance with our MSDS.

  5. What is the miniumum conductivity for Product 655201, PEDOT/PSS?

    The minimum conductivity is 150 S/cm.

  6. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

  7. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  8. Is this PEDOT:PSS, poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate), product p-doped or n-doped?

    This PEDOT:PSS product is based on hole-doped or P-type polymers. PEDOT can be n-doped, but the materials are too unstable to be of any commercial value.

  9. For product 655201, Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate), what is the relationship between film thickness and spin coating speed?

    Please consult this graph showing the spin coating curve for product 655201, Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate).

  10. What is the temperature stability of this poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate), PEDOT:PSS, product?

    Deposited poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate), PEDOT:PSS, films can easily withstand temperatures in excess of 200°C for short duration and around 70°C in continuous service.  The aqueous dispersions of PEDOT:PSS, however, can be damaged by heating above 50°C for a prolonged period.

  11. How do I test the coductivity of poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate), PEDOT:PSS?

    Conductivity measurements should be performed on poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate), PEDOT/PSS, films deposited on flat substrates.  This dispersion should be deposited as a thin and homogeneous layer on a flat substrate using deposition techniques, such as spin-coating or doctor blading.  The layer thickness can be determined by scratching the film off the substrate in places with a razor blade and scanning the stylus of a mechanical or optical profilometer across the scratched region(s). The sheet resistivity can then be measured with conventional four-point probes.

  12. Can PEDOT:PSS, Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate), coatings be etched?

    Yes, applied PEDOT:PSS films can be patterned by laser ablation.

  13. My question is not addressed here, how can I contact Technical Service for assistance?
