摘要: 用溴作为掺杂剂,通过多壁碳纳米管(MWNTs,multi-walled nanotubes)吸附溴提高其电导率,用聚苯乙烯(PS,polystyrene)对MWNT进行修饰改性.用透射电镜(TEM,transmission electron microscope )和扫描电镜(FESEM, field emitting scanning electron microscope)等分析研究,表明在多壁碳纳米管上接枝了高分子聚苯乙烯, PS接枝并没有降低加溴多壁碳纳米管的电导率,且在高分子基体中的分散性得到了明显的改善.Abstract: Bromine,as a dopant was adsorbed onto MWNTs to enhance the electrical conductivity of MWNTs. MWNTs were also modified by polystyrene. TEM and FESEM indicate that the modification of polystyrene improved the dispersion of Br-MWNTs in polymer matrix while the electrical conductivity of Br-MWNTs did not decrease.
