Title: New One-Pot Technique to Introduce Charged Nanoparticles into a Lyotropic Liquid Crystal Matrix
Abstract: We present a new method to incorporate hydrophilic charged nanoparticles the lyotropic liquid crystal (LLC) template. This method is based the effect of the polymer-induced phase separation (PIPS) and of two steps. In the first step, the nanoparticles are mixed a surfactant micellar solution. In the second step, upon addition polymer, phase separation is induced and the LLC phase doped with the is formed. Columnar hexagonal and lamellar LLC templates obtained with the PIPS method. The ordering of the LLC phase can be by the amount of polymer added to induce phase separation. method works both for the system of nonionic surfactants and and ionic surfactants and polyelectrolytes. We demonstrate that PIPS method enables the fabrication of the LLC templates doped with or negatively charged nanoparticles as well as with a mixture of oppositely charged nanoparticles in arbitrary proportions.
