| Abstract: | PLLA/n-HA composite materials were prepared with polylactic acid （PLEA） and nano-hydroxyapatite （HA） as raw materials use bounce dispersion technology. Samples were divided into four groups of composite materials, degrade performance and pH value changes of PLLA/n-HA composite materials in saline were researched. The results show that with the increase of HA content the rate of degradation of the composite reduced and pH value decreas. |
