Piezoelectric and pyroelectric polymer film and process for preparing same |
| 摘要 |
A process for preparing polyvinylidene fluoride type (PVDF) films having highly stable piezoelectricity and pyroelectricity, by stretching PVDF films, while causing corona discharge, across the electric field formed by discharging, to effect thereby to polarization of film.
