In this paper, a novel semi-interpenetrating network material PVP/p(HEMA-co-BA) was synthesized by free radical polymerization of 2-hydroxyethyl methacrylate (HEMA), butylacrylate (BA), polyvinyl pyrrolidone (PVP), and host-guest interaction complex which was synthesized by recognition and free radical copolymerization using cyclodextrin modified aluminium oxide nanoparticles (CD-Al2O3NPS) as host molecules and acrylate containing adamantane as guest molecules. The microstructure and properties of PVP/p(HEMA-co-BA) were characterized and tested. The results show that the material has self-repairing property by the interaction of host and guest materials. And the introduction of two reversible non-covalent interactions host-guest interaction and hydrogen bond gives the material excellent shape memory function. With the shape memory and self-repair capability, the material can repair by itself and recover the original property when the distance between the two sections of the crack is large. In addition, PVP/p(HEMA-co-BA) has good thermal stability and can be used at 200℃ in high temperature environment.
