METHOD FOR SORTING NANOOBJECTS AND AN APPARATUS FABRICATED THEREBY

摘要

A method for sorting nanoobjects from the mixture comprising nanoobjects such as semiconducting and metallic carbon nanotubes and an apparatus fabricated thereby. An embodiment comprises an energy transfer to the mixture in a way that the degree in which nanoonobjects are heated and bonded to the surface of a substance depends on their electrical conductivities. The next embodiment comprises an electrolytic deposition of a material on the mixture in a way that the degree in which nanoanobjects are bonded to the surface of the substance by the deposited layer depends on their electrical conductivities. The above nanoobjects are sorted by selectively separating mostly the weaker bonded nanoobjects from the surface. Another embodiment comprises an energy transfer in a low pressure reactive gas medium to the mixture in a way that the degree in which nanoonobjects are heated and chemically modified depends on their conductivities.
