▎ 摘　　要

NOVELTY - Graphene phase change energy-gathering dispersion comprises 7-15 wt.% graphene, 35-65 wt.% alcohol phase change material, 5-8 wt.% additives, and water (remaining amount). USE - The graphene phase change energy-gathering dispersion is used as heating material for electric heating. ADVANTAGE - The method: enhances heating efficiency of heating device, long service life, safe use, energy saving and environmentally friendly, harmless to the human body, significantly reducing the electricity load of electric heating in winter, reducing the burden on the national grid, and the industrialization has extremely important social and economic significance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene phase change energy-gathering dispersion, comprising (1) adding water to the reactor, (2) adding the additive to the reactor, and heating and stirring, (3) adding graphene into the reactor, and heating and stirring, (4) controlling the temperature to 55-65°C, adding alcohol phase change material, and keeping stirring, and (5) keeping the temperature and allowing to stand to obtain graphene phase change energy-gathering dispersion, which can be filled and stored, preferably in the step (4), keeping stirring for 50-70 minutes, preferably in the step (5), allowing to stand at 10-30°C for 20-30 hours.
