摘要 采用静电纺丝技术制备了聚乳酸(PLLA)/聚己内酯(PCL)/聚乙二醇(PEG)共混纤维膜,考察了溶剂体积比、共混物共混质量比、溶液浓度对电纺纤维形貌的影响,研究了共混纤维膜的热稳定性、结晶性、力学性能及亲水性。结果表明加入PEG有效提高了共混纤维膜的热稳定性和结晶性,提高了共混纤维膜的拉伸强度、弹性模量和亲水性能。 Poly(L-lactide)(PLLA)/poly(ε-caprolactone)(PCL)/polyethylene glycol(PEG) blend fibrous membranes were prepared by electrospinning.The effect of solvent volume ratio,polymer blending weight ratio and solution concentration on their morphology were investigated.Their thermal stability,crystallinity,mechanical properties and hydrophilicity were characterized.Due to the incorporation of PEG,the thermal stability and crystallinity of the fibrous membranes were improved,and their tensile strength,elastic modulus and hydrophilicity were also enhanced.
