METHOD FOR PRODUCTION OF COMPOSITE OPTICAL CHEMOSENSOR FILM

摘要

FIELD: nanotechnologies. ^ SUBSTANCE: invention relates to nanotechnologies, in particular to production of water-resistant and heat-resistant structured chemosensor films on the basis of photon-crystalline opalescent matrix, which may find application in express analysis of hazardous admixtures in gaseous and liquid wastes. Method includes thermal treatment of single-crystal photon-crystalline film with particle size of 185-250 nm at the temperature of 350-500C in air medium for 120-30 minutes accordingly, then impregnation with diluted ethanol nanosol of silica with particle size of up to 8 nm, stabilised with cetyltrimethylammonium chloride and modified with luminescent organic dye, and further drying of produced composite optical chemosensor film. ^ EFFECT: invention makes it possible to produce water-resistant, mechanically strong and heat-resistant films. ^ 2 cl, 2 dwg
