With the progress of science and technology

low-temperature environment is forcing people to enter the territory

and the thermal insulation material

which it is suitable for human body temperature

is the precondition into these areas. Stored energy and phase transition material with its unique energy storage and heat release mechanism have become a hot research topic in today's society. In this paper

the importance of stored energy and phase transition microcapsules

research status in domestic and foreign

were introduced. It was elaborated microcapsule formation process by the soft monomer butyl acrylate (BA) and hard monomer methyl methacrylate (MMA) as the wall material

and the influence of the monomers types on microcapsule morphology

Finally

the development trend of microcapsule and silicone rubber composites was previewed.
