1. A composition comprising:
a gelling agent including an organic amine having two or more functional groups; and a solution having a first type of carbon nanotubes with an affinity or miscibility for inclusion in a gel such that the gelling agent non-covalently cross-links with at least a portion of the first type of nanotubes to form the gel, and a second type of carbon nanotubes with a different affinity or miscibility from the first type of carbon nanotubes such that the first type of carbon nanotubes and the second type of carbon nanotubes are separated through a compaction of the gel causing the second type of carbon nanotubes to be removed as a liquid.
