Frequently Asked Questions

Frequently Asked Questions are available for this Product.

Application

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

PEDOT:PSS polymeric films have been used as a charge dissipation layer in electron-beam lithography and focused ion beam milling. Sample preparation has been reported to be easier and quicker for various substrates, including gallium nitride (GaN) on sapphire (Al2O3) substrates, zinc oxide (ZnO), fused silica, lithium niobate (LiNbO3), silicon carbide (SiC) and diamond (C), spin-coated onto the ITO coated glass substrate. PEDOT: PSS layers have also been reported to be used as anode buffer layer for organic solar cells and as replacements for the transparent conductive coatings of organic solar cells. Various studies report the use of metal modified conductive grade PEDOT: PSS as an anode buffer layer in solar cells, example: copper phthalocyanine/fullerene-based solar cells 4 Conductive PEDOT:PSS combined with polyvinylidene fluoride (PVDF) membranes may be used to prepare PEDOT:PSS-PVDF ionic liquid soft actuators. The function of PEDOT:PSS as a pseudocapacitive material was investigated.

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. 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. Conductive polymer blend. Impact of small electric and magnetic fields on the polymer was studied.

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. 
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, or search here. 
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.
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.
