Patent ID: 8778296

Claim:
A dispersible carbon nanotube comprising a carbon nanotube backbone and an organic moiety covalently bonded to the carbon nanotube backbone, wherein the organic moiety is represented by Formula 1: *-L-Ar—(OH) n Formula 1 wherein * represents a point of attachment to the carbon nanotube backbone, wherein each L is independently selected from the group consisting of —(CR 1 R 2 ) a —, —O—, —NR 3 —, and with the proviso that if present is bonded to another L selected from the group consisting of —O—, —NH—, and —(CR 4 R 5 ) a —; and wherein Ar is a C 6 to C 14 aromatic group; n is 1 to 13; a is 1 to 20; R 1 and R 2 are each independently selected from the group consisting of hydrogen, a hydroxyl group, a cyano group, a halogen atom, and —NH 2 ; R 3 is hydrogen or a C 1 to C 10 alkyl group; R 4 is —H or —NH 2 ; and R 5 is —H.
