| titleOfInvention | A kind of preparation method of polyunsymfluorethylepiezoelectric piezoelectric film |
| abstract | The preparation method that the present invention relates to polyunsymfluorethylepiezoelectric piezoelectric film, belongs to the preparing technical field of new material.The preparation method of the polyunsymfluorethylepiezoelectric piezoelectric film of the present invention is by adding electric field in the process to the Kynoar solution film forming of curtain coating, electric field induces the Kynoar β phase crystallization in Kynoar solution and in the orderly orientation arrangement of direction of an electric field, the polyunsymfluorethylepiezoelectric piezoelectric film making acquisition has a higher piezoelectric constant, improve polyunsymfluorethylepiezoelectric piezoelectric film acoustic-electric conversion and in the environment energy the electromechanical conversion efficiency such as catch.It is an object of the invention to overcome the orderly orientation arrangement that can not reach high β crystal transition and β crystalline phase in the technology of preparing of existing polyunsymfluorethylepiezoelectric piezoelectric film, film forming is separately performed with crystalline phase conversion process, there is provided a kind of simple to operate, the preparation method of the polyunsymfluorethylepiezoelectric piezoelectric film that film forming is synchronously performed with polarization crystal transition, prepared polyunsymfluorethylepiezoelectric piezoelectric film has higher piezoelectric constant. |
