| 摘 要： | 以二甲基亚砜为溶剂,制备不同配比的聚乳酸(PLLA)和聚乙烯醇(PVA)的混合溶液,静电纺丝制得PLLA/PVA纳米纤维。采用红外光谱仪、原子力显微镜等对PLLA/PVA纳米纤维结构与性能进行了表征。结果表明:PLLA/PVA纳米纤维中PVA上的羟基与PLLA上的羰基形成了氢键,PLLA与PVA之间存在一定的相互作用,但PLLA/PVA纳米纤维存在相分离现象;混合溶液的PLLA质量分数为11%,PVA质量分数为8%时可以得到较好的PLLA/PVA纳米纤维,但PVA质量分数为6%时出现液滴及珠丝,PVA质量分数为4%时,不能制得纳米纤维。

| Abstract: | The blend solution of poly(lactic acid)(PLLA)and poly(vinyl alcohol)(PVA)was prepared at different charge ratios with dimethyl sulphoxide as a solvent and was spun into PLLA/PVA nanofibor via electrospinning process.The structure and properties of the PLLA/PVA nanofiber were characterized by infrared spectroscopy,atomic force microscopy,etc.The re- sults showed that as for PLLA/PVA nanofiber,the hydrogen bond was formed from the hydroxyl group of PVA and the carbonyl group of PLLA.There was an interaction between PLLA and PVA.The incompatibility existed in PLLA/PVA nanofiber.The fairly good nanofiber could be produced via electrospinning process from the blend solution contaiming 11% PLLA and 8% PVA by mass fraction.However,the liquid droplets appeared as the mass fraction of PVA was 6%.The nanofiber couldn't be formed as the mass fraction of PVA was 4%. |
