Title: Single-Walled Carbon Nanotube/Lyotropic Liquid Crystal Hybrid Materials by a Phase Separation Method in the Presence of Polyelectrolyte
Abstract: We present a detailed study on the incorporation of single-walled carbon (SWNTs) into lyotropic liquid crystals (LLC) by phase in the presence of polyelectrolytes. Two cases were studied this work: (i) incorporation of SWNTs into the LLC phase formed by an surfactant sodium dodecyl sulfate (SDS) in the presence of an polyelectrolyte poly(sodium styrenesulfonate) (PSS); (ii) of SWNTs into the LLC phase formed by a cationic cetyltrimethylammonium bromide (CTAB) in the presence of a polyelectrolyte poly(diallydimethylammonium chloride) The SWNTs/LLC composites were characterized by polarized microscopy (POM) observations and small-angle X-ray scattering X S) measurements. In both systems, the surfactant phase was into a hexagonal lattice by the polyelectrolyte within the concentration range. Several factors that can influence the of SWNTs/LLC composite were examined, including concentration surfactants and polyelectrolytes and temperature. Aggregated SWNTs not observed, indicating that SWNTs were well dispersed in the LLC SAXS measurements showed the lattice parameter of the host LLC changed upon varying the mixing ratio of polyelectrolyte to ionic The SWNTs/LLC hybrids showed considerable stability against rise in both systems, and desorption of surfactant from SWNTs was not observed at higher temperature.
