Aerogel-based shaped composite phase change material as well as preparation method and application thereof

The invention discloses an aerogel-based shaped composite phase change material as well as a preparation method and application thereof. The phase change material comprises aerogel and an inorganic hydrated salt phase change material loaded in the aerogel, wherein the outer surface of the aerogel is coated with a light-cured resin film. The preparation method comprises the following steps: S1, preparing an inorganic hydrated salt phase change material; s2, adding the inorganic hydrated salt phase change material prepared in the step S1 into a certain amount of aerogel, heating, uniformly stirring, and cooling to room temperature to obtain an aerogel-based phase change material; and S3, spraying organic silicon resin on the surface of the aerogel-based phase change material to obtain the aerogel-based shaped composite phase change material. The aerogel-based shape-stabilized composite phase change material prepared by the invention is high in heat storage capacity, excellent in heat stability and durability, a
