Polymer Composites of Carbon Nanotubes Aligned by a Magnetic Field

Abstract

Anisotropic carbon nanotube–polyester composites have been realized by polymerization of the nanotube–monomer dispersion in a constant magnetic field (see Figure for method). Magnetic susceptibilities, electrical conductivities, and mechanical properties of the composite show clear anisotropy, indicating magnetic field-induced alignment of carbon nanotubes in the polymer matrix.
