Research Abstract

The control of orientation of carbon nanotubes, using a magnetic field is an important technique. Magnetically simulated microgravity can achieve non-vessel conditions and magnetic orientation. We prepared polyvinyl alcohol (PVA) films with multiwall carbon nanotubes (MWCNTs), and we investigated the MWCNT orientation in the simulated microgravity condition. The XRD pattern results and AFM observations showed that the nanotubes were oriented parallel to the surface of the film at the zero field. In contrast, they were oriented perpendicularly in the magnetic field. Moreover, we developed a control technique of the angle between the nanotube and the magnetic field.
Flexible fibers like DNA are many useful functions, but their magnetic orientation was difficult because of the flexibility itself. Through many trial experiments, we prepared a DNA film without a plate, and the results of birefringence spectra showed the DNA chains were perpendicular to the magnetic field.
