摘要 采用抽滤法制备了一种厚度和纳米孔隙可控的碳纳米管薄膜,探讨优化了碳管种类、溶剂、表面活性剂、超声功率等制备工艺参数,并采用扫描电镜、导电测试仪等技术手段对膜材料的孔径尺寸、形貌特征、力学性能、导电性能等进行了测试表征。结果表明:以TNM3型碳纳米管为原料,以去离子水为溶剂,曲拉通为表面活性剂,在超声功率350W条件下制备的碳纳米管膜综合性能最佳。随着超声功率的增加,碳纳米管薄膜的平均孔径尺寸先递减,后又增大;当碳纳米管含量0.55g/L时,其拉伸强度、模量最高,分别为3.1MPa,0.79MPa;体积电阻率为0.045Ω·cm。

Abstract: Carbon nanotube films with the controllable thickness and nano pore were prepared by filtration method.The processing parameters such as the type of carbon nanotube,solvent,surfactant and ultrasonic power were discussed and optimized.The morphology and properties of specimen film including pore size,mechanical properties and electrical conductivity were characterized by SEM,conductive tester and other technologies.The results demonstrated that carbon nanotube film prepared from TNM3,deionized water as solvent,Triton as surfactant and ultrasonic power 350W exhibited the best comprehensive performance.With the increase of ultrasonic power,the average pore size of film decreased,and then increased.Meanwhile,the maximum tensile strength and modulus of film with the content of carbon nanotube 0.55g/L,were 3.1MPa,0.79MPa respectively.The volume resistivity was 0.045Ω·cm.
