| 摘 要： | 通过乙炔催化裂解制得碳纳米管,采用浓硫酸和双氧水的混合溶液对碳纳米管进行表面羟基化修饰,利用化学镀使Pd、Co以及FePt金属纳米粒子成功地吸附在碳管表面,结果发现碳纳米管及其复合物均为介电损耗型介质,Co-碳纳米管复合物相比纯碳纳米管在高频区域有较强的宽范围吸收.

| Abstract: | In this report, the nanoparticals of Pd, Co or FePt were successfully anchored on the CNTs modified with hydroxyl groups which were beforehand treated with hydrogen peroxide and concentrated sulfuric acid.The Co-CNTs composite exhibits better absorption property as compared with the pure carbon nanotubes in a broad range of the high frequency microwave region. |
