| titleOfInvention | Process for producing electret, and electrostatic induction conversion device |
| abstract | To provide a process for producing an electret which has high stability with time and thermal stability of retained electric charge and which has excellent charge retention performance, and an electrostatic induction conversion device comprising such an electret. n A process for producing an electret, which comprises a step of thermally treating a composition comprising a fluorinated polymer and a silane coupling agent, wherein 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. An electrostatic induction conversion device comprising such an electret. |
