摘　　要：碳纳米管由于其独特的物理化学性质在有机分离膜技术中引起了极大关注。综述了碳纳米管的形貌、物理化学性质、碳纳米管的功能化及与其他材料的复合对有机分离膜性能改进的研究进展。碳纳米管形貌产生的快速传输效应有效提高了有机分离膜的过滤通量;碳纳米管良好的物理化学性质为改进有机分离膜的分离性能、机械稳定性、抗污染能力均提供了有利条件;碳纳米管的功能化更是为解决有机分离膜通量和选择性的权衡效应问题发挥了重要作用;碳纳米管和其他材料的复合进一步拓宽了碳纳米管对有机分离膜性能改进的范围。Carbon nanotube has gained a great concern in organic separation membranes due to its extraordinary physical and chemical properties. The progress of improvements in morphology, physical and chemical properties, functionalization and composite with other materials was reviewed. The flux of organic separation membranes was enhanced because of its rapid transmission effect resulted from the morphology of carbon nanotube. The benign physical and chemical properties of carbon nanotube provided advantages for improving the separation property, mechanical stability and antifouling capacity of organic separation membranes. Functionalized carbon nanotube contributed more to overcome the inherent limitation of trade-off between flux and selectivity that any membrane process carried along with. Carbon nanotube composite with other materials further widened the scope of improvement in performances of organic separation membranes.
