Description
Application
Can be cast into a film with a conductivity of 7x10-2 S/cm in the fully hydrated acid form. Films have good optical transparency.
Fuel cell membrane, electrochromic uses, biosensors and anti-thrombogenic and endothealizing coatings.
Packaging
25, 100 mL in glass bottle
Preparation Note
To cast a film:
1. Concentrate solution to 600 centapoise viscosity (typically 6-9 wt.% polymer).
2. Preheat the casting surface to 35 °C. A clean, flat PTFE-coated glass surface is recommended.
3. Secure a silicone release liner to the casting surface.
4. Place a small drop of the polymer solution on the release liner.
5. Draw the polymer solution down the release liner.
6. Dry the film for 30 min. For controlled evaporation it is recommended to cover surface with aluminum foil that has been perforated with small pinholes.
