Fabrication and characterization of microencapsulated n-octadecane with different crosslinked methylmethacrylate-based polymer shells

▶ n-Octadecane was encapsulated with crosslinked methylmethacrylate-based polymer. ▶ Three types of initiator were used at different polymerization temperatures. ▶ Increasing crosslinkable functional moiety of crosslinking agent increased quality. ▶ Microcapsule with pentaerythritol tetraacrylate has the highest latent heats. ▶ Lower polymerization temperatures led to a lower heat capacity.
