Multifunctional Ferromagnetic Carbon-Nanotube Arrays Prepared by Pulse-Injection Chemical Vapor Deposition

摘要

Multiwalled carbon nanotubes (MWCNTs) have received enormous attention during the past decade owing to their potential in the miniaturization of electronic and mechanical devices such as field-effect transistors (FET), logic circuits, field-emission displays, energy storage systems, optoelectronic switch and memory devices. Although the idea of using MWCNTs in microelectromechanical systems (MEMS) is proposed, building highly magnetic MWCNTs architectures remained a challenge in spite of their various applications in micro/nano magnetomechanical systems (MMMS/NMMS), high-flux magnetic separations, and controlled drug delivery.
