Description

Application

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

Used in ITO-free OPV applications as a highly conductive hole transport layer.PEDOT: PSS may be used as a conductive polymer in the fabrication of printable transparent μECoG electrode for optogenetic applications,1 polymer photodetector. 2 PEDOT:PSS molecules were blade coated in organic thin film transistors (OTFTs) to enhance performance with minimum variability. 3

General description

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

Frequently Asked Questions

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.
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.
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 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 a dried film of product739316 (poly(3,4-Ethylenedioxythiophene)-poly(styrenesulfonate)) stable in air in a laboratory environment?
Product739316 (poly(3,4-Ethylenedioxythiophene)-poly(styrenesulfonate)) is susceptible to oxidation and photo degradation, however,our supplier has outlined that this concern is in reference to exposure to strong oxidizing agents and UV light in particular. The product when dried on target will be stable in a typical lab air environment, however, one will notice degradation and lack of conductivity when exposed to UV light, strong oxidizing conditions, heat, and or high humidity for extended periods of time.
Why does product 739316, Orgacon IJ-1005, have a low pH?
Orgacon IJ-1005has a lowpHbecause this ink is intended for use as an HIL (hole-injection layer) in OLED materials. Increasing pH would negatively affect the workfunction, but if you want to print on textiles to obtain conducting lines, you can slightly adjust the pH withamonia or an organic amine base. The ink is in water and typically needs to reach130°C for drying.
What can you tell me regarding the method of preparation of the PEDOT/PSS products, such as Products 768618 and 739316?
The information on the molecular weights of the PEDOT and PSS used to make each batch is held as proprietary.The exact information on the relative amounts(by weight) of the PEDOT and PSS present in these polymersis also held as proprietary. There is a little more PSS than PEDOT; this is logical, since the formula weight for the monomeric equivalent in PSS (C7H6SO3) is a little higher than the formula weight for the monomeric equivalent in PEDOT (C6H4SO2).The solution, product 739316 is made in situ; it is not made from the dry pellets (product 768618).
