Based on reversible photo crosslinkable properties, a series of polymethacrylate derivatives having cinnamoyl group in the side chain has been designed and synthesized. By simple UV irradiation and thermal treatment on these polymer films, a complete healing behavior accompanied by changes of the surface hardness was observed.
