Process for producing electret, and electrostatic induction conversion device |
| abstract |
A process is disclosed for producing an electret, which includes a step of thermally treating a composition including a fluorinated polymer and a silane coupling agent, where the fluorinated polymer has an alicyclic structure in its main chain and has a carboxy group or an alkoxycarbonyl group as its terminal group. The silane coupling agent has an amino group; and the temperature for the thermal treatment is from 250° C. to 330° C. |
