Claim:
1. A process of chemically attaching compounds to carbon nanotubes (CNT's) which comprises: functionalizing the CNTs by reducing the CNTs with alkali metal naphthalene complex or alkali metal benzophenone complex to produce negatively charged CNTs, and subjecting the negatively charged CNTs to nucleophilic substitution reaction in tetrahydrofuran with a compound carrying a functional group, said compound selected from at least one of: an epoxide, succinic anhydride and an organic halide selected from at least one of: 1- bromo (or iodo) dodecane, 1 bromoalcohol, 1-bromoethylene amine, bromocarboxylic acid, bromo-carboxylate ester, and epibromoanhydride, which compound reacts with the negatively charged CNT, whereby the compound chemically bonds to the CNT; or subjecting the negatively charged CNTs to polymerization by addition of polystyrene or methyl methacrylate and epoxide to produce a polymer grafted CNT.
