Application
Cross-linkable solid polymeric electrolyte.

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.
