The influence of emulsifier types of microcapsule phase-change materials

Abstract:Microcapsule phase change material is the particle that the phase change material is formed by the micro encapsulation technology. Micro encapsulated phase change materials can better utilize and exert the unique function of phase change materials.Today's micro encapsulated phase change materials have been applied in many fields, such as aerospace, architecture, clothing, military, agriculture and so on, which have become an important issue in the current society.This thesis selects three kinds of emulsifier,as OP-10, Twain 20 and twelve sodium.The use of thermostatic water bath, thermostatic magnetic mixer, dryer and vacuum pump device synthetic three different microencapsulated phase change materials.The morphology of the coating was observed by electron microscope, and the effect of the package was determined by the thermal gravimetric analyzer.Conclusion the micro encapsulated phase change material made of OP-10 emulsifier is ideal, the surface is smooth, the arrangement is clear, and the shape is good.
