Carbon nanotubes(CNTs) have emerged as one of the most promising electron field emitter due to their high aspect ratio and chemical stability. For such applications, it requires that CNTs be aligned over large-scale. The assembly of CNTs attached nanoparticles is one of the most challenging tasks in alignment of Nanoparticels functionalized CNTs by external field in field effect transistors, field emission devices and polymer composites. Here, we present a novel method for aligning CNTs external fields on the CNTs-attached nanoparticles. The nanoparticles were attached to the CNTs during thermal reaction process. Transmission electron microscope(TEM) revealed the CNTs attached nanoparticles and scanning electron microscope(SEM) results show that the nanoparticles functionalized CNTs align perpendicular to the surface. And we discuss the emission and mechanical properties of those materials as a function of alignment. |
