Recyclable polymer aerogel, cold-storage phase-change composite material, preparation methods and uses

Abstract

A recyclable polymer aerogel, a preparation method therefor, a recovery method therefor, and a use thereof; and a recyclable cold-storage phase-change composite material containing the recyclable polymer aerogel, a recyclable cold-storage phase-change material having a real-time temperature monitoring function, a preparation method therefor, and a use thereof are provided. The polymer in the polymer aerogel contains a maleic anhydride group-containing structural unit and a maleimide group-containing structural unit. The polymer unit is prepared into an aerogel. The recyclable cold-storage phase-change material having a real-time temperature monitoring function has a layered structure comprising an inner layer formed by a recyclable cold-storage phase-change composite material, and an outer layer formed by a second polymer aerogel, and can achieve both large-batch temperature monitoring and recyclability.
