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.

Abstract: Graphene is a single layer carbon-based material known for high strength, high flexibility, high electrical conductivity, high surface area, hydrophobicity and barrier property. Introduction of surface functional groups on graphene enhances most of these properties. A facile and economical process to prepare amine and fluoride functionalized graphenes is disclosed. The disclosed processes utilize direct functionalization of pristine graphene without pre-functionalization (GO). Successful functionalization of both aminated and fluorinated graphenes were confirmed by the analyses of FT-IR, thermal gravimetric analysis (TGA), Raman, UV-Vis, and dispersion study. Amine functional groups can react with epoxy resin and urethane resin to form a covalent bond, and fluorinated graphene can give high hydrophobicity and durability, therefore both can be applied as a material or a component in polymer and composite coatings for corrosion protection, moisture or gas barriers.
