<p>The present invention is directed to methods of forming sidewall- functionalized carbon nanotubes, wherein such functionalized carbon nanotube s have hydroxyl-terminated moieties covalently attached to their sidewalls. Generally, such methods involve chemistry on carbon nanotubes that have firs t been fluorinated. In some embodiments, fluorinated carbon nanotubes ("fluoronanotubes") are reacted with mono-metal salts of a dialcohol, MO-R-O H, where M is a metal and R is hydrocarbon or other organic chain and/or ring structural unit. In such embodiments, -O-R-OH displaces -F on the nanotube, the fluorine leaving as MF. Generally, such mono-metal salts are formed in situ by the addition of MOH to one or more dialcohols in which the fluoronanotubes have been dispersed. In some embodiments, fluoronanotubes ar e reacted with amino alcohols, such as being of the type H2N-R-OH, wherein -N( H)- R-OH displaces -F on the nanotube, the fluorine leaving as HF.</p> |
