▎ 摘　　要

NOVELTY - Manufacturing graphene aerogel phase-change energy storage material comprises subjecting graphene aerogel to oxidation treatment and acidification treatment to obtain hydrophilic graphene aerogel; preparing Glauber's salt phase-change material into liquid state, soaking hydrophilic graphene aerogel, sonicating, evaporating in water bath, and cooling to below 30 degrees C. USE - The method is for manufacturing graphene aerogel phase-change energy storage material. ADVANTAGE - The method eliminates the phase delamination phenomenon of Glauber's salt phase change material, maintains latent heat of Glauber's salt phase change material to above 80% after 500 cycles of use, improves service life of phase change material, and has sub-cooling degree of below 1 degrees C. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a carbon-based nanofluid composite low-temperature mirabilite phase change material comprises 1-10 wt.% carbon-based nanoparticles and 90-99 wt.% Glauber's salt phase change material. The carbon-based nanoparticles are modified hydrophilic nanoparticles; and (2) preparation of the carbon-based nanofluid composite low-temperature mirabilite phase change material comprising mixing hydrophilic nanoparticles and Glauber's salt phase-change material, ball milling, heating to 40-80 degrees C, adding water, dissolving, insulating at 40-80 degrees C for 0.5-1 hour, evaporating through water bath heating, and cooling to below 30 degrees C.
