| Abstract: | A novel composite,composed of nano-hydroxyapatite (n-HA),polyvinyl alcohol(PVA) and gelatin(Gel),was prepared by the method of blending in solution.Water content and burning test were used to analyze the homogeneity of the composites.The materials were also characterized by SEM,EDAX,TEM,IR,XRD and the water absorption rate of the hydrogels with different ratio of nHA/PVA/Gel were tested.The results showed that the prepared hydrogels had good homogeneity and suitable water absorption rate.The n-HA/PVA/Gel hydrogel could be used as an artificial cartilage material. |
