用原位聚合法合成一系列不同滑石粉含量的聚酰胺酸／滑石粉溶液，再将其热酰亚胺化制备出聚酰亚胺／滑石粉复合薄膜。

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。
