Abstract: Network polyurethane shell microencapsulated phase change materials (MicroPCMs) were
successfully prepared by an interfacial polymerization method using isophorone diisocyanate (IPDI) and
triethanolamine (TEA) as monomers. The effect of core/shell mass ratio on the surface morphology and
particle size distribution of MicroPCMs was investigated. In addition, TEA dosage was varied to investigate
its effect on the surface morphology, chemical structure, thermal stability and compactness of MicroPCMs.
The results showed that the prepared microcapsules were spherical with smooth and contact surface, and the
surface cave of microcapsules disappeared when the core/shell mass ratio was greater than 2.73∶1.00.
When the core/shell mass ratio was 2.73∶1.00, the TEA dosage was 3.5 g, the prepared MicroPCMs had
good thermal stability and compactness, which could withstand high temperature of 200 ℃, and the mass
loss was 5.52% after drying at 120 ℃ for 6 h. The MicroPCMs had an obviously thermal energy storage
performance, and the melting temperature (T m) and melting enthalpy (H m) were 22.5 ℃ and 86.37 J/g,
respectively.
