Abstract

The invention belongs to the field of an organic-inorganic composite material and particularly relates to a polyvinyl carbazole intercalated hydrotalcite fluorescent film and a preparation method thereof. The poly(N-vinyl carbazole) and p-tert-butyl benzoic acid radical intercalated hydrotalcite film has a supermolecular structure, the crystal structure of the poly(N-vinyl carbazole) and p-tert-butyl benzoic acid intercalated hydrotalcite film is a crystal structure of hydrotalcite-like materials, the chemical formula of the poly(N-vinyl carbazole) and p-tert-butyl benzoic acid intercalated hydrotalcite film is [(M<2+>)[1-x>](M<3+>)][x](OH)2]<x+>(PTBBA<->)[x](PVK)[y].mH2O. By utilizing a benzene ring-enriched hydrophobic environment provided by p-tert-butyl benzoic acid radicals among hydrotalcite layers, the poly(N-vinyl carbazole) with excellent fluorescence property can be assembled among the hydrotalcite layers, in-situ polymerization can be realized under the irradiation of a mercury lamp, and the poly(N-vinyl carbazole) intercalated hydrotalcite film material can be prepared. The material is stable in intercalated structure, high in mechanical strength, and strong in corrosion resistance, obvious fluorescence is seen in a visible light area, and the polyvinyl carbazole intercalated hydrotalcite fluorescent film has wide application prospects as an optical material.
