METHOD FOR MANUFACTURING ELECTRET MATERIAL BASED ON FLUOROPOLYMER

摘要

FIELD: electret materials.;SUBSTANCE: invention relates to the field of technologies for the manufacture of electret materials and products based on them, it can be used for the manufacture of electroacoustic and electromechanical converters, electret filters for gas purification. A method for manufacturing an electret material based on a fluoropolymer includes applying a fluoropolymer membrane to a metal electrode, synthesizing vanadium-containing structures on its surface by sequentially treating the polymer matrix with vanadium oxychloride vapor, drained carrier gas, then water vapor, then, drained carrier gas again, and electretting the fluoropolymer membrane in a positive corona discharge.;EFFECT: simplification of the manufacturing technology of electret materials.;1 cl, 1 dwg, 2 ex
