Bowl-shaped organic silicon thermal energy storage phase change microcapsule and preparation method thereof

The invention provides a bowl-shaped organic silicon thermal energy storage phase change microcapsule and a preparation method thereof, and relates to the technical field of nano material preparation. The preparation method of the bowl-shaped organic silicon thermal energy storage phase change microcapsule comprises the following steps: adding an organic silane coupling agent into an acid solution with a preset pH value, and mixing and reacting the reactants to obtain a first reaction solution; adding an oil phase solution dissolved with a phase change material into the first reaction solution, and mixing the solutions to obtain a second reaction solution; and adding a base catalyst into the second reaction liquid to react to obtain the bowl-shaped organic silicon thermal energy storage phase change microcapsule. The preparation method is an organic whole, and has the advantages of simple process, mild reaction conditions (only stirring or ultrasonic treatment and the like at 50-70 DEG C), low preparation raw
