    Abstract: A double-inverse opal photonic crystal resin film is formed by embedding nanospheres in pores of polyacrylate inverse opal framework material and then filling the pores of the double-inverse opal photonic crystal resin film with an ethanol solution with hydrophilic acrylamide dissolved therein followed by photopolymerization to form a polyacrylamide network, so as to obtain the double-inverse opal photonic crystal resin film using water as ink. A mass fraction of hydrophilic acrylamide in the ethanol solution is 2 to 8 wt.%. The resin film can induce water to penetrate into the pores of the double-inverse opal photonic crystal resin film, making the nanospheres in the pores of the inverse opal framework distribute from random to order under the action of buoyancy force, thereby eliminating scattering interference and producing brilliant structural colors by regulating refractive index contrast.

    Abstract: The present invention relates to the technical field of new materials, and relates to a thermal conduction enhanced organic composite shape-stabilized phase change material and a preparation method thereof. A thermal conduction enhanced organic composite shape-stabilized phase change material, which is composed of a coordination crosslinked network polymer, an organic solid-liquid phase change material and a thermal conduction enhancer, the mass percent are as follows: coordination crosslinked network polymer 1-50%, organic solid-liquid phase change material 40-98.9%, and thermal conduction enhancer 0.1-10%, the coordination crosslinked network polymer being formed by complexing of polymer compound with metal ions. The invention has simple synthesis process and convenient applications, the material having large enthalpy of phase change, excellent shape stabilizing effect, while the phenomenon of liquid leakage will not occur during operation. The material has broad application prospects in the field of thermal energy storage and management.
