The invention belongs to the technical field of film materials, and particularly relates to a transparent heat-insulating
ultraviolet-proof
composite film based on a photonic
quasicrystal material anda preparation method thereof. The
composite film structurally comprises a transparent substrate layer, a photonic
quasicrystal functional film layer, an
adhesive layer and a strippable layer. The photonic
quasicrystal film is formed by
polymer core-shell-structure microspheres and
infrared functional nanoparticles which are stacked and arranged in a three-dimensional ordered manner through a specific process, and has adjustable structure color and
optical transparency. The structural color, transparency and
ultraviolet and
infrared blocking
wavelength range of the film can be regulated and controlled by regulating and controlling the core
microsphere size, shell thickness and
refractive index of the core-shell-structure microspheres and the content of the
infrared functional nanoparticles, and the
ultraviolet and infrared blocking efficiency can also be controlled by regulating and controlling the thickness. The formed
composite film is high in
ultraviolet light blocking efficiency, high in visible light
transmittance and good in heat insulation effect, and has excellent transparent heat insulation ultraviolet-proof and explosion-proof performance, and can be used for
energy conservation, explosion prevention and the like of automobiles and building glass.
