Activation method for carbon nanotubes and method for preparing conductive heat shrink tubes

The invention discloses an activation method for carbon nanotubes and a method for preparing conductive heat shrink tubes. The method for activating the carbon nanotubes comprises the following steps:S1, putting carboxylated carbon nanotubes, a catalyst, a molecular sieve and dichloromethane into a container and magnetically stirring to obtain a mixture; S2, after adding an enamine type reagent into the mixture, continually magnetically stirring to react; and S3, washing and filtering the mixture after the reaction is finished, so as to obtain activated carbon nanotubes. The carbon nanotubeswith good electrical conductivity are chemically modified and are grafted on heat shrink tube matrix materials to prepare the antistatic heat shrink tubes with excellent electrical conductivity. 本发明公开了一种碳纳米管的活化方法及制备导电热缩管的方法，活化碳纳米管的方法包括如下步骤：S1、将羧基化碳纳米管、催化剂、分子筛、二氯甲烷置于容器中进行磁力搅拌，得到混合物；S2、在所述混合物中加入烯胺类试剂后继续进行磁力搅拌反应；S3、将反应结束后的所述混合物洗涤过滤得到活化后的碳纳米管。本发明将具有良好导电性的碳纳米管化学改性，并将其接枝在热缩管基体材料上，制备具有优异导电性能的抗静电热缩管。
