| Abstract: | A novel composite,composed of nano-hydroxyapatite （n-HA）,polyvinyl alcohol （PVA） and so- dium alginate （SA）, 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, IR, XRD and the water absorption rate of the hydrogels with different ratio of PVA was tested. The results show that the prepared hydrogels have even composition and there are interaction between components with good homogeneity and suitable water absorption rate. The n-HA/PVA/SA hydrogel can be used as an artificial cartilage material. |
