摘要：

HA/PVA composites at different weight ratios were prepared by in situ growth of HA crystallites in PVA gels, and some interesting shape memory behaviors were investigated. Those results showed that HA/PVA composites at a weight ratio of 1: 20, 1: 10, and 1: 5 had desirable shape memory effects. The initial shapes of pure PVA and HA/PVA composites were recovered automatically in 40 s and HA particles in PVA-matrix composites played an important role during the shape memory recovery.
