The application is based on electrochromic material technology, and particularly relates to an electrochromic visible-infrared response super surface film and a preparation method thereof. The preparation method comprises the following steps: step-by-step magnetron sputtering, depositing a conductive layer, tantalum pentoxide and tungsten oxide film on a substrate in sequence to form a device bottom electrode, a dielectric layer and an electrochromic layer; based on a mask, the film is subjected to a gluing-photolithography process, the electrochromic layer is etched by an argon ion beam to realize super surface pattern preparation; and the film is subjected to an annealing process in an air atmosphere to crystallize the tungsten oxide layer. The application has good visible-infrared compatible response performance, and simultaneously realizes visible color change and high variable emissivity in an infrared wave band (2.5-15 mu m).

The application discloses a transparent heat-insulating energy-saving window film master batch and a preparation method and window film thereof. The transparent heat-insulating energy-saving window film master batch comprises nanometer fluorinated tungsten bronze powder, polydimethylsiloxane, a dispersing agent and a polymer carrier. The nanometer fluorinated tungsten bronze powder is a core-shell structure composed of nanometer tungsten bronze particles externally grafted with fluorine-containing silane. The molecular structure of the nanometer tungsten bronze is M x WO3, 0.01<=x<=0.30, the mass ratio of the fluorine-containing silane and the nanometer tungsten bronze powder is 1:201:15. The fluorination modification of the surface of the nanometer tungsten bronze can improve the agglomeration of the nanometer tungsten bronze, ensure that the particle size of the modified powder is less than or equal to 100 nm in the plastic product, improve the infrared blocking rate and the visible light transmittance, improve the 8-13 mu infrared emissivity, and make the nanometer tungsten bronze have the effect of radiating heat. Meanwhile, by controlling the mass ratio of the fluorine-containing silane and the nanometer tungsten bronze, the compatibility of the powder in the polymer carrier can be improved, and the powder has high 8-13 mu infrared emissivity.
