碳纳米管接枝共聚物合成及结构研究

Study on synthesis and structure of carbon nanotube graft copolymers

碳纳米管的修饰和功能化是制备碳纳米材料改性聚合物基复合材料的必要前提。通过对碳纳米管的羧酸化、酰氯化和醇化等一系列处理过程,分别在碳纳米管表面接枝—COOH、—COCl、—OH等官能团,经与丙烯腈单体反应而生成碳纳米管接枝共聚物。

The modification and functionalization of carbon nanotubes is a necessary prerequisite for the preparation of polymer based composites modified by carbon nano-materials.The surface of the carbon nanotube was grafted with functional groups such as —COOH,—COCl,—OH etc.through a series of processes including carboxylated,acyl chlorination and alcoholization etc.And the graft copolymers of carbon nanotubes were synthesized by reaction with acrylonitrile monomer.
