Microwave induced functionalization of single wall carbon nanotubes and composites prepared therefrom

摘要

The invention is directed to a method of forming, producing or manufacturing functionalized nanomaterials, and, specifically, soluble functionalized nanomaterials. The presently described invention also relates to nanomaterial-based composites consisting of a target material, which can include ceramic, polymer, or metallic matrices incorporated into or grown on nanomaterials, as well as a method or synthesis technique for the formation, production, or manufacture of nanomaterial-based composites through microwave-induced reaction.

1. A method for synthesizing a carbon nanomaterial composite comprising:
providing a substantially non-soluble carbon nanomaterial and at least one functionalizing reactant, the at least one functionalizing reactant including an acidic solution; delivering the substantially non-soluble carbon nanomaterial and the at least one functionalizing reactant to a microwave vessel; closing and sealing the microwave vessel; positioning the closed and sealed microwave vessel in a microwave reactor; subjecting the nanomaterial and the at least one functionalizing reactant to a first set of microwave conditions via the microwave reactor so that after the nanomaterial and the at least one functionalizing reactant are subjected to the first set of microwave conditions while in the closed and sealed microwave vessel, the nanomaterial is: (i) functionalized, and (ii) substantially soluble in a solvent; removing the functionalized and soluble carbon nanomaterial from the microwave vessel; dispersing at least a portion of the functionalized and soluble carbon nanomaterial in a solution containing a target precursor material to form a uniform dispersion of functionalized carbon nanomaterial in the solution; delivering the solution containing the carbon nanomaterial and the target precursor material to the microwave vessel; closing and sealing the microwave vessel; positioning the closed and sealed microwave vessel in the microwave reactor; subjecting the solution of the target precursor material and carbon nanomaterial to a second set of microwave conditions via the microwave reactor to reactively synthesize said carbon nanomaterial composite, the synthesized carbon nanomaterial composite having synthesized target material formed on the dispersed carbon nanomaterial; wherein the synthesized target material completely covers and surrounds areas of the dispersed carbon nanomaterial in the synthesized carbon nanomaterial composite.
