A novel nonoxidative method for preparation of functionalized multiwalled carbon nanotubes (MWCNT) has been developed based on a UV sensitive initiator for atom transfer radical polymerization (ATRP). The method has been investigated with respect to ligands and polymerization time for the preparation of polystyrene functionalized MWCNT. It was found that pentamethyldiethylenetriamine (PMDETA) gave
基于用于原子转移自由基聚合(ATRP)的紫外线敏感引发剂,开发了一种新型的非氧化方法,用于制备功能化的多壁碳纳米管(MWCNT)。已经研究了关于配体和聚合时间的方法,以制备聚苯乙烯官能化的MWCNT。发现五甲基二亚乙基三胺(PMDETA)在较短的聚合时间内以较高的负载量给出了优异的结果。已对在两种不同等级的未氧化MWCNT上应用的方法进行了比较研究,说明了反应性和聚合物负载量的巨大差异,强调了选择MWCNT起始材料的重要性。除苯乙烯外,聚甲基丙烯酸乙二醇酯(PEGMA)也显示出从MWCNT的表面聚合。最后,给出了聚苯乙烯或聚苯硫醚复合材料的初步结果。©2010 Wiley Periodicals,Inc.
