POLYETHYLENE TEREPHTHALATE-BASED FILM MATERIAL Russian patent published in 2007 - IPC B32B9/04 B82B1/00 B01D69/12 C08J7/04 H01G9/00 

FIELD: polymer materials.

SUBSTANCE: invention relates to composite materials based on high-molecular weight carbon-involving compounds and can be used for anodes of electrolytic condensers made from dielectric elastic film with current-conducting coating. Polyester-based film material has nano-sized metallic coating. A diamond-like layer 5-50 nm thick is disposed between modified surface of polyester base and metallic coating and, on the surface of metallic coating, spongy aluminum layer is deposited having surface development factor within a range of 80 to 400. Diamond-like nanolayer is characterized by sp3 hybridization of amorphous carbon atoms, amorphous carbon being deposited in vacuum from gas phase under action of ion-plasma source.

EFFECT: increased specific electrical capacity of condenser due to increased operation voltages and adhesion between high-developed surfaces of functional film coating nanolayers.
