The in situ growth of 3D net-like CNTs on C fiber

Carbon nanotubes (CNTs) with 3 dimensional net-like structure were perfectly grown on C fiber at ambient temperature and pressure using a modified electrochemical process, and their composition and morphology were characterized by Raman spectroscopy, Energy dispersive spectroscopy (EDS), High resolution transmission electron microscopy (HRTEM), and Scanning electron microscopy (SEM), respectively. This paper also reported the influence of applied voltage and reaction time on the formation and growth of CNTs, and proposed a possible growth mechanism. - Highlights: • CNTs with 3D net-like structure were grown on C fiber by an "electrochemical" route. • The formation and growth of CNTs relied on applied voltage and reaction time. • A possible growth mechanism was proposed.
