Liquid crystal clay composites
We report a successful method of sterically stabilising small, high aspect ratio clay platelets in a, liquid crystalline host using a quaternary ammonium surfactant. Small Angle X-ray Scattering results for the dry powder 2HT-treated Laponite show that there is a monolayer of 2HT on the platelet surface. The data for the Laponite suspension in 5CB indicate free tumbling disks which do not aggregate in the nematic phase.
