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.[1] 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.[2][3] Impact of small electric and magnetic fields on the polymer was studied.[4]
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
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),[5] spin-coated onto the ITO coated glass substrate.[6] PEDOT: PSS layers have also been reported to be used as anode buffer layer for organic solar cells[2] and as replacements for the transparent conductive coatings of organic solar cells.[7] 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 [2][3][6]4 Conductive PEDOT:PSS combined with polyvinylidene fluoride (PVDF) membranes may be used to prepare PEDOT:PSS-PVDF ionic liquid soft actuators.[8] The function of PEDOT:PSS as a pseudocapacitive material was investigated.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers.

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

Can I use this dispersion for making a PEDOT:PSS channel of OECT(Organic Electrochemical Transistor) using spin coating? Code -483095
1 answer-
PEDOT:PSS can be applied for spin coating and Organic Electrochemical Transistors (OECTs). Here is a paper working on PEDOT:PSS based OECTs: https://www.sciencedirect.com/science/article/pii/S095656632100138X.
Unfortunately, 483095 hasn't been tested for that application, but it is worth trying.Helpful?

1 answer-
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.

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