一般描述

这些是无催化剂的电弧放电多壁碳纳米管（MWNT）。多壁碳纳米管核心由熔融碳壳包围，其余为多层多边形碳纳米粒子和无定形石墨碳纳米粒子。它含有约5-20个石墨层。

应用

MWNT已用于碳纳米材料的氧化处理比较研究。MWNT在CNT/SiC纳米复合材料中可被用作一种增强材料。2
多壁碳纳米管（MWNT）属于碳材料类，具有良好的热机械和电化学性质。这种材料可用于多种可持续能源应用，如太阳能电池、光催化、生物传感器、气体传感器、超级电容器，另外也可用作强化填料以改善复合材料的机械性质。

外形

大约 5-20 层石墨。多壁碳纳米管芯被熔融的碳壳围绕，剩余的为多层多边形碳纳米粒子以及无定形和石墨碳纳米粒子。
