Highly-transparent ultraviolet-resistant energy-saving film and preparation method thereof

The invention relates to a highly-transparent ultraviolet-resistant energy-saving film and a preparation method thereof, belonging to the field of composite films synthesized by compounding polymer and inorganic nano-particles and aiming at overcoming the defects that the prior film has low visible light transmission and high production cost. The highly-transparent ultraviolet-resistant energy-saving film comprises the following components by the weight percent: 50-99.8 of organic polymer, 0.2-50 of metal-oxide nano-particles and 0-39.9 of polymer auxiliary agent. The highly-transparent ultraviolet-resistant energy-saving film is prepared by a solution mixing method or a solution-melting mixing method; with the solution mixing method, the organic polymer and the metal-oxide nano-particles are dispersed in dispersing medium to prepare film preparing stock solution, and the film preparing stock solution is used for preparing the energy-saving film on a substrate; with the solution-melting mixing method, the mix
