▎ 摘　　要

NOVELTY - Graphite oxide is dissolved in water, stirred, and ultrasonically processed to obtain graphene oxide solution. A phase change material is added to obtained graphene oxide solution, heated to melt the phase change material melting, and stirred to obtain graphene oxide-covered stable pickering liquid phase change material. To the obtained product, acid is added, and pH is regulated to 2-3 to form graphene oxide capsule wall which is then cooled to obtain graphene oxide phase change microcapsules. USE - Preparation of graphene oxide phase change microcapsules (claimed). ADVANTAGE - The method efficiently and economically provides graphene oxide phase change microcapsules having high heat coefficient, by simple method.
