Microwave-Assisted Chemical Functionalization of Single-Walled Carbon Nanotubes with Organic Peroxides

Microwave-assisted chemical functionalization of single-walled carbon nanotubes, with undecyl groups de-composed from lauroyl peroxides was reported. This rapid efficient procedure reduced the reaction time to 10 min, and obtained the products with higher functionalized degree than that by the conventional refluxing method. The in-fluence of different reaction time and microwave power on the functionalized degree has been explored by using FT-IR, TGA and Raman analyses. The results show that longer treatment time will lead to partial defunctionaliza-tion, and higher microwave power (higher than 900 W) can reduce the functionalized degree by removing some ini-tially-attached functional groups. Dispersion stability images and HRTEM images show that the resulting SWNT has enhanced dispersivity in organic solvents compared to the pristine nanotubes.
