Title:
RECYCLABLE POLYMER AEROGEL, COLD-STORAGE PHASE-CHANGE COMPOSITE MATERIAL, PREPARATION METHODS, AND USES
Document Type and Number:
WIPO Patent Application WO/2024/051811
Kind Code:
A1
Abstract:
The present invention relates to the field of porous materials, and in particular to 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 comprising 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. The polymer in the polymer aerogel comprises a maleic anhydride group-containing structural unit and a maleimide group-containing structural unit. According to the present invention, the polymer comprising a maleimide-containing structural unit is prepared into an aerogel for the first time, and the application range of maleic anhydride-containing and maleimide-containing copolymers is widened. In addition, the aerogel prepared in the present invention has extremely high recovery efficiency; after dissolution and recovery by aqueous ammonia, the recovery efficiency may be higher than 99%; and the aerogel preparation and recovery process does not need any organic solvent and has the characteristics of high efficiency with low energy consumption and environmental friendliness. The recyclable cold-storage phase-change composite material can be recycled, achieves less leakage, and can keep a low temperature for a long period of time. 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.
