Patent ID: 7220818

Claim:
A composition of matter comprising a polymer having the formula: wherein x is from 5 to 100; R 1 is a linear or branched alkyl group having from 1 to 19 carbon atoms or a linear or branched alkoxy group having from 1 to 19 carbon atoms; R 2 is a linear or branched alkyl group having from 1 to 19 carbon atoms or a linear or branched alkoxy group having from 1 to 19 carbon atoms wherein R 1 and R 2 may be the same or different; R 3 is CH or N; and R 4 is O(CH 2 )y-FG where y is 0 to 20 and FG is a functional group selected from the group consisting of H, F, Cl, Br, OH, SH, NH 2 , CO 2 H, amino acids, sugars, DNA fragments, steroids, CO 2 R and CONHR, where R is an alkyl group; and nanotubes, wherein said nanotubes are functionalized by said polymer.
