Pyroelectric and isotropic piezoelectric polymer blends |
摘要 |
A pyroelectric and isotropic piezoelectric polymeric film, the film being formed from a blend of polyvinylidene fluoride and at least one polymer miscible therewith, and prepared by forming the film, heating it to a temperature sufficient to render the film substantially amorphous, cooling at a rate and to a temperature sufficient to prevent crystallization, and polarizing the film to render same beta -crystalline and pyroelectric and isotropically piezoelectric.
