Processing single-walled carbon nanotubes (SWNT) and single-layer graphene (SLG) into thin films or composite nanomaterials are key issues to take advantage of their mechanical, electrical and optical properties. In this talk, we will review our recent results, and primarily optical spectroscopy studies (absorption, Raman and photoluminescence), of the dispersion and orientation of SWNT and SLG in aqueous inks [1-10] as well as the properties of liquid crystals [1-3], thin films [3-5] or composites [6-7] prepared from these inks.
