Hi! All
I was wondering if anyone has advice on filtering/storage of Pedot-PSS. We purchased the high conductivity solution (about 10-100 ohm/square) from Aldrich and stored it in a fridge.
We now notice (after a few months of storage) that pedot is precipitating on the sidewalls. Also, filtering it using nylon/pvdf filter/cellouse nitrate paper (tried 0.2micron and 5 micron) seems to be problematic...
I would appreciate any ideas on optimal storage (room temp?) and filtering procedures for this material. Further, in there data on the change viscosity and other parameters with filter size?
