CNTs have attracted considerable attentions to their potential applications in the emission materials, because of their high aspect ratio, high emission current density and chemical stability. Here, we investigate the effect of alignment and emission properties of a magnetic particle attached – CNTs (MP-CNTs), in which the magnetic nanoparticles were constructed via thermal decomposition in high boiling solvent by metal chloride and sodium oleate. The nanoparticles were attached to the CNT surface during thermal reaction process. We show that the monodisperse magnetic particles are successfully attached to the surface of CNTs. Effect of the magnetic fields on the alignment of the MP-CNTs was investigated, showing that the MP-CNTs align perpendicular to the device surface. We also discuss the alignment behavior of the MP-CNTs incorporated into amorphous polymers. |
