摘要
运用静电纺丝技术制备了聚乳酸纳米纤维和聚乳酸/磷酸钙复合纳米纤维。对两种电纺纳米纤维的表面形态进行了扫描电子显微镜(SEM)的表征及单轴拉力测试表征。讨论了聚乳酸纳米纤维和聚乳酸/磷酸钙复合纳米纤维的力学性能。结果表明掺加了磷酸钙的聚乳酸纳米纤维的力学性能得到明显提高。
PLA nanofibers and PI.A/calcium phosphate composite nanofibers were prepared by eleetrospinning technology. The morphology of the two kinds of nanofihers were characterized by scanning electron microscopy (SEM). The mechanicaI properties of the PLA nanofierbs and pLA/Calcium Phosphate composite nanofihers were characterized by uniaxial tensile test respectively. And the properties of the PLA nanofibers,and PLA/Calcium Phosphate composite nanofibets were discussed. The result demonstrated the mechanical properties of PLA nanofibers mixed with calcium phosphate were increased.
