An easy and economically viable route for the decoration of carbon nanotubes by magnetite nanoparticles, and their orientation in a magnetic field

摘要

A simple, cheap and tunable approach for the decoration of carbon nanotubes by magnetite nanoparticles and their orientation in a magnetic field is reported.Carbon nanotubes(CNTs)have unique electronic,mechanical,thermal and chemical properties that justify the steadily increasing attention paid to them.1 Chemical functionalization of CNTs by non covalent and covalent bonding of organic molecules is extensively studied in order to improve dispersion in both liquid phases and polymer matrices.Insofar as they can be individualized,positioned and oriented onto surfaces,CNTs can find applications in nanoelectronics.
