摘　　要： 通过方便、经济的浸渍-干燥法将单壁碳纳米管涂覆于棉和尼龙表面制备了导电织物。扫描和透射电镜分析表明,含碳纳米管的涂层厚约3μm。用导电棉制备化学电阻器,当与氨气接触后,电阻器电阻值迅速增加,表现出良好的感应性能,这主要与氨气分子与碳纳米管间的电子转移有关。用导电尼龙制备了柔性电容器,当用作能量存储元件时具有能耗低、效率高的优点。 The conductive fabric is fabricated by coating sing-wall carbon nanotube onto the surface of cotton and nylon via the simple and economic immersion-drying approach. The SEM and TEM results show that the thickness of the coating containing carbon nanotube is 3 m. For the chemical resistor made from conductive cotton, the resistance value increases rapidly when contacting with ammonium, exhibiting good sensing capability. It is mainly attributed to the electron-transfer process between ammonium and carbon nanotube. In addition, the flexible chemical resistor made from conductive nylon shows low-energy consumption and high efficiency.
