| 摘 要： | 采用静电纺丝技术制备聚乳酸(PLA)微/纳米纤维膜,研究了其可纺性、浸润性能及结构。结果表明:以二氯甲烷为溶剂的PLA电纺丝溶液,当PLA质量分数为7%时,可纺出纤维直径为280～690 nm的PLA微/纳米纤维膜。PLA微/纳米纤维膜与水的接触角为127.6°,高于PLA流延膜与水的接触角107.7°;红外光谱分析表明,PLA微/纳米纤维膜的分子组成没有发生变化;X光电子能谱测试表明PLA微/纳米纤维膜的表面碳氧含量比高于PLA流延膜,PLA微/纳米纤维膜的疏水性得到提高。

| Abstract: | Polylactic acid(PLA)micro-and nano-fiber membranes were prepared by electrospinning.Their spinnability,wet- tability and structure were studied.The results showed that the PLA micro-and nano-fiber membrane can be prepared with the diameter of 280-690 nm from PLA electrospinning solution with 7% PLA by mass fraction using methylene chloride as solvent. The contact angle between the fiber membrane and water was 127.6°,higher than the contact angle between cast film and water 107.7°.The infrared spectra showed that no transformation was observed in the molecular composition of PLA micro-and nano- fiber membrane.X-ray photoelectron spectroscopic analysis showed that the PLA micro-and nano-fiber membrane had higher carbon-and-oxygen ratio on the surface than PLA cast film,and the hydrophobicity of PLA micro-and nano-fiber membrane was improved. |
