METHOD OF PRODUCING METAL-CONTAINING NANOCOMPOSITES Russian patent published in 2011 - IPC B29C41/00 B82B3/00

Abstract RU 2412050 C1

FIELD: process engineering.

SUBSTANCE: invention relates to methods of producing polymer nanocomposites, namely, metal-containing nanocomposites and may be used in production of materials with unusual properties for various branches of industry. Proposed method comprises adding metal nanoparticles to polymer matrix, and deposition of vapors of one or several metals in vacuum. Note here that vapors of said metals are deposited on the surface of polymer film in amount of 10¹⁴-10¹⁶ metal atoms per 1 cm² of the surface. Then, polymer film containing deposited metal is melted, the melt being mixed and granulated. Note here that metal content in produced metal-containing nanocomposites is regulated by repeating deposition and melting and/or varying surface-to-area ratio in initial polymer film.

EFFECT: ruling out agglomeration of separate nanoparticles, uniform sizes and distribution of said particles, simplified procedure and ease of production.
