一般描述

通过化学气相沉积（CVD）制备多壁碳纳米管（MWNT，CNT）。在化学气相沉积 (CVD) 中，挥发性前体在高温下发生热分解形成固体沉积物。1多壁碳纳米管的直径在 110-170 nm 之间，长度在 5-9 μm 之间。多壁纳米管在温度高达3697℃的惰性气体中是稳定的。

应用

多壁碳纳米管（MWNT）属于碳质材料，具有良好的物理化学、热机械和电化学特性。这种材料可用于各种可持续能源应用，如太阳能电池、光催化、生物传感器、气体传感器、超级电容器，并可用作强化填充物增强复合材料的机械性能。
研究了碳纳米管对人结肠直肠癌细胞系 (Caco-2)、人乳腺癌细胞系 (MCF-7)、人肺腺癌 Calu-3 细胞和近端支气管气道浆液细胞的毒性和免疫效应。这些多壁碳纳米管被用来设计三维，独立多孔碳结构。自支撑结构在储能、超级电容器、光伏电池、场发射器件、传感器和高性能催化剂等领域具有广阔的应用前景。聚苯乙烯/多壁碳纳米管 (MWNTs) 纳米复合材料的制备及其电学和光学性能的研究。此外，还报道了铂/ MWNT /钴酸盐纳米复合材料的制备。
