静电纺丝改性聚丁二酸丁二醇酯的制备及其性能的研究

Preparation and performance of modified poly(butylene succinate) by electrospinning

采用共混法结合静电纺丝技术制备出PBS/淀粉纳米纤维,考察淀粉含量对PBS的影响。结果表明,随着淀粉含量的增加,纤维的直径略增加,加入淀粉并未影响PBS的分子结构,PBS和淀粉在不同的温度产生了热降解,纳米纤维的可降解性逐渐提高;PBS/淀粉纳米纤维亲水性随可溶性淀粉含量的增大而提高。

Poly（butylene succinate）（PBS）/soluble starch were fabricated by blending method combined with electrospinning technology,the effect of starch content was examined.The results showed that with the increasing of starch content,the nanofibers diameter of fiber increases slightly,starch to join did not affect the structure of molecules,PBS and starch are degraded in their respective temperature area,nanofibers can improve biodegradability gradually.PBS/Starch nanofibers hydrophility is increased with increasing the content of soluble starch.
