【摘要】 利用热拉伸获得不同性能与结构形态的PGLA(GA/LA摩尔比=90/10)纤维,并进行体外降解实验。在降解过程中,采用DSC、傅里叶红外光谱、扫描电镜等测试手段对PGLA(90/10)纤维的性能与形态变化进行研究。结果表明,热拉伸显著改变PGLA(90/10)纤维的降解特征。更多还原

【Abstract】 The PGLA(GA/LA molar ratio= 90/10) fibers with different properties and structural morphologies were obtained by heat-stretching treatment and were tested in vitro degradation.In the degradation process,the structures and properties of the PGLA(90/10) fiber have been investigated by means of DSC,infrared spectroscopy,scanning electron microscopy and other testing methods.The results show that,heat drawing can vary the degradation characteristics of the PGLA(90/10) fibers significantly.更多还原
