Composite aerogel, recyclable heat-storage phase-change composite material with photothermal conversion function, and preparation methods therefor and use

Abstract

A composite aerogel, a recyclable heat-storage phase-change composite material with a photothermal conversion function are provided. The composite aerogel has a polymer and graphene. The polymer contains a maleic-anhydride-group-containing structural unit and a maleimide-group-containing structural unit. The composite aerogel can be used as a carrier to load a phase-change material, so as to obtain a recyclable heat-storage phase-change composite material, which has a photothermal conversion function and can also be recycled. The recyclable heat-storage phase-change composite material contains a composite aerogel and a phase-change material loaded in the composite aerogel.
