CHEN Baocheng, QIN Shuang, ZHANG Xu, et al. Study on preparation process of high-voltage electrothinfilm based on PVDF[J]. 2019, (10): 33-35+43. DOI: 10.13873/j.1000-9787(2019)10-0033-03.
Aiming at the present situation that domestic polyvinylidene fluoride(PVDF) piezoelectric sensor only is restricted in the laboratory stage
massive imports are still needed.The preparation technology of PVDF piezoelectric sensor is studied by analyzing the piezoelectric characteristics of PVDF and combining the structure of sensor products.The preparation process parameters of the main processes such as initial film preparation
uniaxial tensile
high pressure polarization and magnetron sputtering in the process are explored.Sensitive PVDF piezoelectric film is obtained and polyimide materials are used for packaging
PVDF piezoelectric sensor is achieved.Key parameters of the sensor
static piezoelectric coefficient d
33
is test
the results is 13 PC/N.PVDF pi
ezoelectric sensor products satisfied practical engineering is obtained.
