Original Magnetic Alignment of a Nematic Phase Containing Single-Walled Nanotubes
Abstract:Dispersions of single-walled carbon nanotubes in a 4-pentyl-4′-cyano-biphenyl nematic liquid crystal matrix are studied by X-ray scattering. For some mixtures, the addition of nanotubes strongly modifies the properties of the matrix: under a magnetic field, the nematic director is aligned perpendicular to the field, whereas it is parallel to it for pure 4-pentyl-4′-cyano-biphenyl. This original modification of liquid crystal alignment by the addition of nanotubes raises new questions about nanotubes and liquid crystal interactions.
