以聚乳酸(PLLA)/二氯甲烷为单一溶剂体系，采用热-非溶剂诱导相分离技术，成功制备了具有纳米孔结构的新型聚乳酸(PLLA)纤维膜。为了制备纳米多孔纤维膜，需要一个水浴接收器。结果表明，在较宽的湿度范围内均可制得纳米多孔纤维膜。与无孔PLLA纤维膜相比，纳米多孔纤维膜对亚甲基蓝的比表面积提高了约20%，截留率提高了约3倍。此外，制备的聚乳酸纳米多孔纤维膜的水通量在L m−2 h−1下达到4836.6，比非多孔纤维膜提高了25%。此外，聚乳酸纳米孔纤维膜的吸油量可达26.8g−1。通过热-非溶剂诱导相分离技术开发的聚乳酸纳米孔纤维膜在吸油和有机染料过滤方面将显示出良好的前景。
A novel polylactic acid (PLLA) fiber membrane with nanoporous structures has been successfully developed via thermal-nonsolvent induced a phase separation technique by electrospinning a single solvent system of PLLA/dichloromethane. A water bath receiver was necessary for preparing the nanoporous fiber membranes in this paper. The results showed that the nanoporous fiber membranes could be obtained within a wide range of humidity. Compared with non-porous PLLA fiber membranes, the nanoporous fiber membranes displayed significantly improved specific surface area (improved about 20%) and rejection ratio (about 3 times) toward methylene blue. Besides, the PLLA nanoporous fiber membranes showed a water flux up to 4836.6 L m−2h−1, increased by 25% than that of the non-porous fiber membranes. In addition, the oil adsorption capacity of the PLLA nanoporous fiber membranes could reach 26.8 g g−1. The new developed PLLA nanoporous fiber membranes via thermal-nonsolvent induced phase separation technique would demonstrate an impressive prospect for oil adsorption and organic dye filtration.
