  • Pyroelectric and isotropic piezoelectric polymer blends
    Patent number: 4820586
    Abstract: 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.
    Type: Grant
    Filed: October 26, 1987
    Date of Patent: April 11, 1989
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Dennis L. Krueger, Neil W. Loeding, Claudia I. Poser
  • Pyroelectric and isotropic piezoelectric polymer blends
    Patent number: 4615848
    Abstract: A pyroelectric and isotropic piezoelectric polymeric film, the film being formed from a blend of polyvinylidene fluoride and at least one polymer miscible therewith at a temperature above the melting point of the polyvinylidene fluoride, and a process for preparing the film comprising 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 pyroelectric and isotropically piezoelectric.
    Type: Grant
    Filed: February 15, 1985
    Date of Patent: October 7, 1986
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Dennis L. Krueger, Neil W. Loeding, Claudia I. Poser
