采用环氧树脂作为前驱体溶胶，利用负载有碳纳米管的铝板为接收基板，通过简单方便的静电纺丝协同拉拔技术，宏量制备了碳纳米管/环氧树脂复合纤维棉，并对这种复合纤维棉的吸油性能进行了探索。采用扫描电子显微镜(SEM)、热重分析仪(TGA)、压汞仪、拉曼光谱仪等设备系统分析了复合纤维棉的形貌、结构和组成。结果表明，复合纤维棉具有高的比表面积与孔隙率，碳纳米管均匀地分布在复合纤维棉中。复合纤维棉与水和植物油的接触角分别为114.1°与66.8°；与丙纶纤维相比较，复合纤维棉展现出更加优异的吸油能力，可吸附超过自身质量10倍的油类物质。

Carbon nanotubes/epoxy resin (EP) cellucotton composite was prepared on a large scale using EP as the precursor sol, aluminum plates covered with carbon nanotubes as substrate, by a simple and convenient electrospinning and collaborative pulling technology. The morphology, structure and composition of the obtained samples were investigated with scanning electron microscopy, thermogravimetric analyzer, mercury injection test and Raman spectroscopy. Carbon nanotubes were partly wrapped and distributed evenly on the surface of the EP fibers, and the composite structures had high specific surface area and porosity. The contact angle of the carbon nanotube/EP composite structure was 114.1° for water, and 66.8° for vegetable oil. The as-made carbon nanotubes/EP composites showed superior adsorption capacity for vegetable oil, which was better than polypropylene fiber, and could adsorb more than 10 times of oil in terms of their own mass.
