| titleOfInvention | A kind of lead-free BaTiO3-PVDF composite film and preparation method thereof |
| abstract | The invention discloses a lead-free BaTiO 3 -PVDF composite film and a preparation method thereof; the lead-free BaTiO 3 -PVDF composite film contains BaTiO 3 twins. The preparation method is as follows: use BaTiO 3 twin powder as raw material; add appropriate amount of BaTiO 3 twin powder into N,N dimethylformamide solution containing PVDF, mix evenly and spread it on a glass slide, and vacuum After drying and quenching treatment, a BaTiO 3 twin-PVDF composite film was obtained. The preparation method disclosed by the invention simply and effectively enhances the electromechanical coupling piezoelectric performance of the lead-free BaTiO 3 -PVDF composite film, and simultaneously enhances its dielectric and ferroelectric performance. The present invention proposes and prepares the BaTiO 3 twin-PVDF composite film for the first time, which has excellent performance, simple preparation process, and is convenient for large-scale application. |
