Patent ID: 11524484

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 ΔT. When T1=50-100° C. and the base layer and the protective layer reach thermal equilibrium, ΔT=0.15T1−0.35T1.
