We have fabricated carbon nanofibers and nanotubes using disk‐rod assemblies of lyotropic liquid crystals in which the orientation of graphene layers can be manipulated using surface anchoring techniques common to liquid crystal displays. The bulk material properties of the graphene can be controlled by the spatial arrangement of the layers due to their anisotropic nature. We have also demonstrated a method to pattern arrays of nanotubes using an automated printing technique. Carbon nanotubes are being considered for a number of display applications.
