Abstract: A transparent heat-insulating film is provided, wherein the transparent heat-insulating film includes a base layer including a first surface and a second surface, a hard-coat layer, a silver nanowire layer, and a protective layer including an inner surface and an outer surface. The hard-coat layer and the silver nanowire layer are disposed between the first surface of the base layer and the inner surface of the protective layer. A temperature of the second surface of the base layer is T1 (° C.), a temperature of the outer surface of the protective layer is T2 (° C.), and a temperature difference between T1 and T2 (T1?T2) is ?T. When T1=50-100° C. and the base layer and the protective layer reach thermal equilibrium, ?T=0.15T1?0.35T1.

Abstract: A nanometal dispersion and a method for preparing a nanometal dispersion are provided. The method comprises mixing a metal seed crystal aqueous solution, a polysaccharide aqueous solution, and a metal compound aqueous solution, followed by allowing the resulting mixture to conduct a reduction-oxidation reaction to form a nanometal. The produced nanometal dispersion comprises a polysaccharide and a nanometal. The polysaccharide is composed of N-actyl-D-glucosamine and glucuronic acid, and the nanometal has multimorphology.
