METHOD OF FORMING NANOCOMPOSITE COATING ON POROUS ALUMINIUM OXIDE LAYER Russian patent published in 2011 - IPC C01F7/00 B82B1/00 G03C1/74 

FIELD: chemistry.

SUBSTANCE: porous aluminium oxide layer with thickness of 20-30 mcm is formed via anodic treatment in aqueous solutions of acids of aluminium or alloys thereof, saturated with aqueous solution of a silver salt with concentration of 10^-4-10^-2 M/l, dried, treated with aqueous solution of potassium or sodium bromide, dried, treated with ultraviolet radiation and then with hydroquinone developer in order to form in the aluminium oxide pores silver particles whose dimensions do not exceed 20-70 nm and which do not exceed the diameter of aluminium oxide pores. Concentration of potassium bromide is equal to 10^-2-10^-1 M/l.

EFFECT: invention enables to produce a nanocomposite coating on porous aluminium oxide.
