摘要：

The synthesis and characterization of double-walled carbon nanotubes (DWCNT) functionalized with Br2 (Br-DWCN) under microwave assisted (MiW) conditions, to link covalently the Br atoms to DWCNT with a percentage of functionalization of carbon 5-8 % in weight has been demonstrated. 30 mg of DWCNT were mixed with 5 ml of an aqueous solution of Br2 in a 10 ml glass tube. The ability to functionalize carbon nanotube (CNT) through controlled structural modifications is an essential prerequisite for application purposes, which may lead to increased solubility and processability. Raman investigations revealed a certain degree of functionalization of Br-DWCNT, accounting for a mild alteration of the graphic π conjugated surface. A preliminary metal catalyzed cross-coupling reaction made with Br-DWCNT suggests new modified CNT-based precursor could open new synthetic possibilities for designing novel functionalized CNT.
