NOVELTY - Preparation of titanium dioxide loaded graphene base phase change microcapsule involves dissolving graphene oxide in organic solvent, ultrasonically dispersing to prepare graphene oxide solution, placing phase change material in three-necked flask, adding organic solvent and surfactant, stirring to obtain emulsion, placing three-necked flask in a constant temperature oil bath, setting the reaction temperature, adding solution to three-necked flask and adding catalyst to stir graphene oxide to the surface of phase change material droplet. USE - Method for preparing titanium dioxide loaded graphene base phase change microcapsule (claimed). ADVANTAGE - The method is simple. The product has good heat preservation effect and excellent light catalysis property. DETAILED DESCRIPTION - Preparation of titanium dioxide loaded graphene base phase change microcapsule comprises: (A) dissolving graphene oxide in organic solvent and ultrasonically dispersing to prepare graphene oxide solution; (B) placing phase change material in three-necked flask, adding organic solvent and surfactant and stirring to obtain emulsion; (C) placing three-necked flask in a constant temperature oil bath, setting the reaction temperature, adding solution to three-necked flask, adding catalyst to stir graphene oxide to the surface of phase change material droplet; and (D) cooling mixed solution, treating at constant temperature, dropwisely adding tetrabutyl titanate, adding deionized water and acetic acid, reacting, filtering, washing and drying in vacuum oven to reduce graphene oxide.
