Role of Lyotropic Liquid Crystals in Templating Mesosilica Materials

Here we consider the lyotropic liquid crystals and their role in templating scaffolds of mesoporous silica materials. It was 1992 that a Mobil Research group disclosed method to produce particles having regular network pores with hexagonal cubic symmetries. The proposed as liquid-crystal 'templating' mechanism. Since symmetries resulting are those observed mesophases crystals, supposed presence directly process. discuss it reported what is today defined true or direct LCT approach. will be stressed that, any case, surfactant-assisted can better supramolecular method. template mainly happens form modified Stöber In this framework, curvature silica-surfactant interfaces considered, phases analyzed depth related surfaces zero mean discussed detail.
