General description
PEDOT:PSS has high electrical conductivity and good oxidation resistance, the properties which make it suitable for electromagnetic shielding and noise suppression. Thus, the polymeric film formed possesses high transparency throughout the visible light spectrum and even in near IR and near UV regions, displaying virtually 100% absorption from 900-2,000 nm. No absorption maximum from 400-800 nm was observed.

How to Find a Lot/Batch Number for COA
Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.
Aldrich Products
For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').
For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').
For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.
Not Finding What You Are Looking For?

Is a dried film of product 739316 (poly(3,4-Ethylenedioxythiophene)-poly(styrenesulfonate)) stable in air in a laboratory environment?
Product 739316 (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-1005 has a low pH because 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 with amonia or an organic amine base. The ink is in water and typically needs to reach 130°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 polymers is 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).
