CNTs were first pre-treated using acid solution (HNO3) to obtain CNTs functionalized with carboxylic groups. Subsequently, the stearyl alcohol was grafted onto CNT with the assistance of dehydrating agent, N,N'-dicyclohexyl-carbodiimide. Excellent dispersion in organic solvents such as acetone, THF, and chloroform was found for the modified CNTs (CNT-C18). In addition, the PBS/CNTs nanocomposites were then prepared through simple melt-blending. Mechanical properties, thermal behavior, conductivity of resultant polymer/CNT composites were investigated. The results show that excellent dispersion of nanotubes in the PBS matrices was achieved.
为了增加多壁奈米碳管在复合材料中的分散性,将碳管表面进行化学修饰,首先将多壁奈米碳管浸入HNO3溶液中,进行酸化,使碳管表面带有羧酸的官能基,然后再加入十八烷醇,在温和的条件下,藉由N,N'-二环己基碳二亚胺(N,N'-dicyclohexyl- carbodiimide,DCC)脱水剂脱水,使碳管和十八烷醇之间产生酯基的化学键结,改质后的碳管可以分散在acetone、THF、chloroform…等有机溶剂中,结果显示成功的利用DCC脱水剂完成碳管的改质。
