摘要
Electrospinning is a versatile and popular method for the fabrication of ultrafine fibers and many parameters in electrospinning can be adjusted when ideal micro/nanofibers are required.In particular,the selection of a proper solvent condition is a fundamental and crucial step to produce electrospun ultrafine fibers.In this study,a commonly used biomaterial,polylactic acid(PLA),was dissolved in 7 different solvents and PLA micro/nanofibers were prepared by electrospinning.The morphology,porosity,mechanical property and static contact angle were characterized to determine the quality of the obtained product.The results show that different solvent conditions have a significant effect on both the diameter,surface smooth degree of PLA micro/nanofibers and the properties of the fibrous membranes.
