Abstract:
1. A method comprising: a) introducing one or more defects onto one carbon nanotube type or chirality that is part of a mixture of carbon nanotubes by treating said mixture of carbon nanotubes with H b) reacting said carbon nanotube type or chirality comprising said one or more defects with an alkylating agent selected from the group consisting of dimethyl sulfate, diethyl sulfate, di-n-propyl sulfate, methyl-p-toluenesulfonate, ethyl methanesulfonate, n-propyl methanesulfonate, methyl bromide, ethyl bromide, n-propyl bromide, methyl iodide, ethyl iodide, n-propyl bromide, methyl iodine, and benzyl bromide, wherein covalent functionalization of said carbon nanotube type or chirality propagates from said one or more defects to produce a covalently functionalized carbon nanotube type or chirality having alternating sections of functionalized and intact regions of said covalently functionalized carbon nanotube.
