ABSTRACT:
The invention pertains to high-molecular compound-based composite materials using carbon and can be used for anodes of electrolytic capacitors made on the elastic dielectric film base with current-carrying coating.Polyester-base film material chiefly of polyethylene terephthalate has nanodimensional metal coating.New is that a diamond-like layer 5-50 nm thick is placed between the modified surface of the polyester base and metal coating and a sponge metal layer 0.5-20 μm thick is made on the metal coating surface, said sponge metal layer has a surface development factor within the range of 80-400 and the diamond-like nanolayer is sp3-hybridization of amorphous carbon atoms gas-phase deposited in vacuum by means of a ion-plasmous source.The proposed film material with a wide range of electrophysical properties is intended to be used in microelectronics and radio engineering as versatile constructional material. In particular, when used as an anode of the electrolytic capacitor its specific electric capacity is increased due to increased working voltages and adhesion between highly developed surfaces of functional nanolayers of film coating.
