METHOD FOR MANUFACTURE OF METAL CLUSTERS-CONTAINING FILM MATERIALS Russian patent published in 1994 - IPC

FIELD: electronics. SUBSTANCE: paired atoms of metals and p-xylilene (or its derivatives) are vacuum co-condensed to the substrate apt to be cooled to low temperatures. The reactive p-xylilene monomer is pyrolitically obtained from p-cyclophane in vacuum. The low-temperature co-condensate is brought to a stable condition by heating to room temperatures. As an alternative to this method UF-exposure can be practiced so that p-xylilene is polymerized with the formation of poly-p-xylilene and the metal atoms along with small clusters are aggregated to form larger clustered particles which growth is restricted by the resulting film-forming polymeric material containing metal particles the size of several tens of angstroms ( 10^-8cm ). A great variety of metals can be used among them alkaline-earth, transition metals noble and rare-earth ones and their combinations. The resulting films have their thickness varying from decimal fractions to tens of microns with metal content being in the range of 0.1-10 percent by weight. The films reveal interesting dielectric characteristics ( ). EFFECT: providing high-quality absorbing and reflecting system suited for various radiation ranges. 2 tbl, 1 dwg
