Excellent thermal stability P(BeA-co-MMA) microcapsules with high thermal energy storage capacity

Copolymer P(BeA-co-MMA) microcapsules with uniform sphere are successfully synthesized from BeA and MMA through suspension polymerization. The long n-alkane side chain of copolymer derived from BeA form crystal microcells at room temperature and change into random with the temperature increasing, which provides energy storage capacity. This crystal transition is kept in microcells by polymer main chains as skeleton structure on nano-scale. The strong interaction force between shell and core parts overcomes the shortage of core leakage and ensures the excellent thermal durability.131
