ELECTROCHEMICAL PRECIPITATION OF NANOSTRUCTURED CARBON FILM ON CURRENT-CONDUCTING MATERIALS Russian patent published in 2014 - IPC C25D9/02 B82B3/00

Abstract RU 2519438 C1

FIELD: chemistry.

SUBSTANCE: method of electric precipitation of carbon film of fulleroid type on product from current-conducting material includes electric precipitation of carbon, with electric precipitation of carbon being carried out on anode from solution of polyhydroxylated fullerene with concentration 0.100-0.120 g/l in acetone or ethyl alcohol by impact of direct current with density 1.0-2.0 mA/dm² with difference of potentials of electrodes 6.0-8.0 V at temperature 20-30°C and duration of electric precipitation 30-60 min with obtaining said film on product, after which it is washed, dried and heated in oxygen-free atmosphere at temperature 300±30°C.

EFFECT: film represents dense, homogeneous in structure, quality protective biocompatible coating, insoluble in organic solvents and stable to impact of diluted solutions of acids and alkalis.
