Method of making free-standing polyimide film |
| abstract |
Disclosed is a method of making a free-standing polyimide film. A solution is prepared of a polyamic acid 20 to 98 % imidized in an organic solvent and a coating of the solution is applied to a non-stick substrate. The coating is heated to a temperature high enough to evaporate all but 1 to 20 wt.% of the solvent and form a film. The film is removed from the substrate and is heated to evaporate the solvent to less than 1000 ppm. |
