Abstract
We have prepared stable colloidal suspensions in a lyotropic liquid cr ystal exhibiting an isotropic-nematic-lamellar phase sequence. Small a ngle neutron scattering (SANS) and dynamic light scattering (DLS) stud ies show the existence of attractive interparticle interactions in the nematic phase, which lead to a gas-liquid transition of the particles . The resulting liquid phase is weakly anisotropic. Further, the nemat ic-lamellar transition of the liquid crystal is found to be accompanie d by a liquid-solid transition of the particles.
