Abstract:
1. A polymer composite which comprises one or more base polymers, one or more functionalized m-phenylenevinylene-2,5-disubstituted-p-phenylenevinylene polymers, and carbon nanotubes; wherein at least a portion of the one or more functionalized m-phenylenevinylene-2,5-disubstituted-p-phenylenevinylene polymers forms an aggregate with at least a portion of the carbon nanotubes; wherein the one or more functionalized m-phenylenevinylene-2,5-disubstituted-p-phenylenevinylene polymers are m-phenylenevinylene-2,5-disubstituted-p-phenylenevinylene polymers having the formula: wherein n is an integer indicating the number of repeating units in the polymer; R 1 and R 2 independently are selected from the group consisting of an optionally substituted alkenyl group, an alkyl ether group, and an optionally substituted alkyl group; wherein the substituents on the alkenyl or alkyl group are one or more groups selected from the group of consisting of halogens, OH groups, —COX groups, COOR 3 groups, —COO − groups, —N(R 3 ) 2 groups, —N(R 3 ) 3 + groups, epoxy groups: and —Si(R 5 ) 3 groups; wherein X is a halogen or an activated ester group, each R 4 independently is H or an alkyl group, and each R 3 and R 5 is independently selected from the group consisting of hydrogen, an alkyl group, an alkenyl group, a halogenated alkyl group, and a halogenated alkenyl group; and wherein at least one of R 1 and R 2 is a group other than an unsubstituted alkyl group.
