▎ 摘　　要

NOVELTY - Preparing magnetically oriented phase change nanoparticles comprises (1) dissolving a dibasic acid with more than ten carbon atoms in an organic solvent, adding 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and N-hydroxysuccinate, adding mixture of imide or the mixture of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and 1-hydroxybenzotriazole, reacting at room temperature for 10-60 minutes to obtain a mixed solution, (2) adding the amino-modified magnetic graphene oxide into the mixed solution, reacting at room temperature for 24-72 hours, centrifuging, washing and drying to obtain magnetically oriented phase change nanoparticles. USE - The method is useful for preparing magnetically oriented phase change nanoparticles. ADVANTAGE - The method has the recycling and separating function under the magnetic field, it not only has the heat storage function but also has magnetic property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for magnetic-guidance phase-change nano-particle prepared by above method.
