Application

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

Suitable for OTFT applications. PEDOT: PSS conductive ink was used for inkjet printing on a surface modified polyethylene terephathalate.1 It was used as a substrate coating in a heterojunction solar cell. 2 PEDOT: PSS may be used to fabricate a self-powered strain sensor based on ZnO/PEDOT: PSS hybrid structure on a flexible polystyrene substrate. 3 It is also suitable for OTFT applications.

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 conductivityand 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. Conductive polymer blend.1,2 Impact of small electric and magnetic fields on the polymer was studied.

My question is not addressed here, how can I contact Technical Service for assistance?
Use the option to the right to "Ask a Question" by email of a Technical Service Scientist.
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 see the attached chart 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?
Deposited poly(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.
