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.
Bromine as a dopant was adsorbed onto MWNTs to enhance the electrical conductivi- ty 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.
