A generic and material-independent dry route based on electrostatic force directed assembly (ESFDA) is used to assemble various nanoparticles onto multiwalled carbon nanotubes (CNTs). Charged and nonagglomerated aerosol nanocrystals are first produced using a mini-arc plasma source and then delivered in an inert carrier gas to electrically biased CNTs. The electric field near the CNT is significantly enhanced, and the aerosol nanoparticles are attracted to the external surface of CNTs. For the first time, CNTs have been sequentially coated with nanoparticles of multiple materials to realize the multicomponent coating. High resolution transmission electron microscopy images show that the nonagglomerated entity of nanoparticles and the crystallinity of both nanoparticles and CNTs are preserved during the assembly. The ESFDA technique enables unique hybrid nanostructures attractive for various energy applications.
