摘      要：Nano-hydroxyapatite reinforced poly（vinyl alcohol） gel（nano-HA/PVA gel） composites has been proposed as a promising biomaterial,especially used as an articular cartilage repair *** this paper,nano-HA/PVA gel composite was prepared by in situ synthesis method and incorporation with freeze-thaw cycle *** microstructure and morphology were investigated by X-ray diffraction,TEM,SEM and *** results showed that the size of HA particles synthesized in PVA solution was on the nanometer *** the size and crystallinity of HA particles synthesized in PVA solution decreased compared with that of HA synthesized in distilled *** nano-HA particles were distributed in PVA matrix uniformly due to the effect of PVA solution as a dispersant while low content of HA particles in the *** the contrary,with high content of nano-HA particles in the composites,the particles tended to *** result of FT-IR analysis indicated that the chemical bond between nano-HA particles and PVA matrix *** conformation and degree of tacticity of PVA molecule changed because of the addition of HA ***,the interfacial strength of the composites was improved due to the interaction between nano-HA particle and PVA matrix and this was beneficial to improving the mechanical properties of the composites.
