Abstract
Disclosed herein are embodiments of methods for preparing aminated or alkylaminated CNTs wherein the aminated or alkylaminated CNTs are obtained in a reaction by reacting the CNTs with an aminating or alkylaminating reagent in a non-hazardous solvent or a non-hazardous solvent-deionized water mixture. The CNTs may be single-walled, double-walled or multi-walled CNTs. The disclosed processes for amination and alkylamination do not require treatment with concentrated acid, and with the use of solvent, the CNTs and aminating compound or alkylaminating compound are mixed thoroughly throughout the reaction.
