METHOD OF PRODUCTION OF THE PIEZOFILM MATERIALS Russian patent published in 2006 - IPC B29D7/00 B29D7/01 B29C71/04 H01L41/18 

FIELD: chemical industry; methods of production of the piezofilm materials.

SUBSTANCE: the invention is pertaining to the method of production of the piezofilm materials out of the high-molecular thermoplastic polymers, copolymers and their mixtures. The piezofilm materials may be used in the different kinds of the instruments and devices. The method provides for production of the non-oriented film, operations of its orientation, polarization, action of the ionizing radiation and the repeated polarization. Then the polarized film is additionally exposed to the action of ultraviolet irradiation before and-or after the ionizing radiation with the subsequent polarization after each kind of action. The technical result of the invention is improvement of the energy parameters of the produced material.

EFFECT: the invention ensures improvement of the energy parameters of the produced material.
