The invention discloses a preparation method of a strawberry-like thermochromic
energy storage material, comprising the steps of (1) mixing
styrene,
divinyl benzene,
acrylic acid,
glycidyl methacrylate,
polyvinylpyrrolidone and paraffin, adding an emulsifier and an initiator, cooling, and centrifuging to obtain pure phase-change microspheres; (2) mixing a leuco body dye, an electronic
acceptor compound and a
solvent to form a mixture, heating the mixture, mixing well to obtain a solution, adding deionized water,
tetraethyl orthosilicate, a
silane coupling agent and an emulsifier, adding
ammonia water under
ultrasound to allow reacting, centrifuging,
drying at low temperature to obtain thermochromic
silicon capsule particles; (3) mixing the phase-change microspheres and the thermochromic
silicon capsule particles to obtain a mixture, adding an emulsifier and a catalyst to allow reacting, centrifuging, and
drying to obtain the strawberry-like thermochromic
energy storage material. The strawberry-like thermochromic
energy storage material has the advantages of high
enthalpy, high thermosensitive response speed, irreversible color variation, cyclic repetitive color variation, good property stability and the like, can act as a novel intelligent material, and has a good application prospect in the fields, such as building,
energy conservation,
environmental protection, apparel, and medical services.
