摘要: 通过静电纺丝的方法制备出左旋聚乳酸/氟尿嘧啶复合纳米纤维膜,考察了氟尿嘧啶的添加比例、左旋聚乳酸的质量分数对复合纳米纤维成型性的影响,并对其进行力学性能以及润湿性能的测试,结果表明:随着左旋聚乳酸的质量分数的增加,复合纳米纤维直径变粗;氟尿嘧啶的添加比例增加后,纤维直径变细。力学性能测试表明,复合纳米纤维膜的强力、伸长率以及断裂功随着药物添加比例的增加而减小;润湿性能测试表明复合纳米纤维膜的亲水性随着药物添加比例的增加而增加,与此同时,复合膜的异质不均匀性也随之增加。

Abstract: PLLA/FU composite nanofiber membranes were prepared by electrospinning. mass fraction of PLLA,ratio of Fluorouracil and spinning voltage were discussed. The mechanical properties and surface wettability were also studied. The results showed the diameters of the composite nanofiber membranes were increased with the increase of PLLA mass fraction, the diameters decreased with the increase of ratio of Fluorouracil. The mechanical performance testing showed the tensile strength , the elongation and rupture work of the composite were all less than PLLA nanofiber membranes, with the increase of the FU content ,these p erformances were more weaker .The wetting property testing showed the wettability of the composite were increased with the addition of the drug, but their heterogeneity were also increased.
