By suspension polymerization, phase change material microcapsule was synthesized with capsule-core of octadecane, and P (MMA- co - SMA) as the phase change microcapsule wall. Mass production of the MicroPCMs with big phase change enthalpy value and high thermal stability can be realized. Its performance was analyzed by using scanning electron microscope (SEM), differential scanning calorimetry apparatus (DSC), etc. Influence of emulsifying speed and emulsifying time on the thermal enthalpy and output of batch prepared phase change microcapsules was discussed.
