Description

Application

Virtually 100% absorption from 900-2,000 nm. No absorption maximum from 400-800 nm. Conductive polymer blend.

PEDOT:PSS is an intrinsically conductive polymer (ICP) that can be coated on various substrates and nanostructures like fullerenes (C60) to form a composite with high electrochemical properties for applications like low cost printed electronics, optoelectronics and polymeric solar cells. It can also be used as a conductive hydrogel with polyethylene glycol-diacrylate (PEG-DA) for potential applications in tissue engineering.

USA customers: 1-800-325-3010 orview local office numbers.
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.
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.
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).
What is the temperature stability of this poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate), PEDOT:PSS, product?
Depositedpoly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate), PEDOT:PSS, films can easily withstand temperatures in excess of 200 deg C for short duration and around 70 deg C in continuous service.The aqueous dispersions of PEDOT:PSS, however, can be damaged by heating above 50 deg C for a prolonged period.
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.
Can PEDOT:PSS, Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate),coatings be etched?
Yes, applied PEDOT:PSS films can be patterned by laser ablation.
My question is not addressed here, how can I contact Technical Service for assistance?
