摘　　要：通过喷涂法将碳纳米管复合液均匀喷涂于聚四氟乙烯(PTFE)亲水膜表面,制备性能优良的染料废水过滤膜。利用场发射扫描电镜、接触角测定仪以及孔径分析仪等对膜的表面形貌结构、接触角以及孔隙率进行分析,评定膜的综合性能。将复合膜用于染料废水过滤试验,发现其对亚甲基蓝(MB)以及中性红染料(NR)的过滤效果优良,能有效地过滤油水乳液,且添加TiO2粒子后能更好地提高复合膜对废水的过滤性能。In order to prepare a filtration membrane with excellent dye filtration performance,the carbon nanotube composite liquid is uniformly sprayed on the surface of PTFE hydrophilic membrane.Then,the surface morphology,contact angle and porosity of the membrane are analyzed by field emission scanning electron microscopy,contact angle tester and pore size analyzer to evaluate the comprehensive performance of the membrane.The dye wastewater filtration experiment is carried out on the composite membrane.The results show that the composite membrane has excellent filtration efficiency on MB and NR dyes,and can effectively filter the oil-water emulsion.The addition of TiO2 particles can significantly improve the filtration performance of the composite membrane for wastewater.
