METHOD OF FILM ELECTRET PRODUCTION Russian patent published in 2013 - IPC H01G7/02 B82B1/00

Abstract RU 2477540 C2

FIELD: electrical engineering.

SUBSTANCE: according to the method for film electret production involving application of a fluoropolymer layer on the metal electrode surface with subsequent electreting, a discrete layer is applied on the fluoropolymer surface consisting of nanosized aggregates of titan-containing nanostructures isolated from each other. This technical solution usage enables increase of positive charge surface density in fluoropolymers more than 1.9-2.2 times and to increase charge temporal and thermal stability.

EFFECT: increase of magnitude and stability of positive charge surface density in film fluoropolymers.
