Application of Magnetically Simulated Microgravity for Preparation of Thin Films with Carbon Nanotubes

A poly(vinyl alcohol) (PVA) thin film in which multiwall carbon nanotubes (MWCNTs) were included was prepared in a magnetically 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.
