Optical, spectroscopic and phase state properties of systems with supra-particle structure based on carbon nano-tubes

摘要

Systems, based on aqueous suspensions of single walled carbon nanotubes, stabilized by surfactants, and having supramolecular ordering are studied by spectroscopy and polarized microscopy. Nonlinear optical behavior of the suspensions has been checked. A correlation between sizes of aggregate in suspension and nonlinear optical limiting parameters has been found. A nematic meso-phase based on suspension of carbon nanotubes has been obtained.
