METHOD OF FILM ELECTRET PRODUCTION

摘要

FIELD: electricity.SUBSTANCE: method involves application of a fluoropolymer layer onto a metal electrode, application of a discrete layer consisting of isolated nano-sized aggregates out of titan-containing nanostructures onto the fluoropolymer surface, and further electreting in positive corona discharge. Prior to the application of titan-containing nanostructures the fluoropolymer surface is treated by plasma of high-frequency capacitive discharge in the atmosphere of saturated water vapour. The usage of this technical solution enables increase of positive charge surface density in fluoropolymers by at least 1.45 times and increase charge temporal and thermal stability.EFFECT: increase of magnitude and stability of positive charge surface density in film fluoropolymers.2 dwg, 5 ex
