Janus nanoparticles liquid cristal phases and derived materials

Obiettivo

Textured materials opens definitive new possibilities for preparing new materials in various fields such as catalysis, optics, pharmacy. Recently, formation of mesoporous silicate and aluminosilicate molecular sieves from a self assembly process involving liquid crystal templates has been demonstrated to be promising materials. Unfortunately, these materials, prepared by conventional precipitation routes showed amorphous structures. These materials prepared by a precipitation route, developed amorphous mineral walls, and are not stable at crystallization temperatures. Producing textured materials for applications in catalysis, optics, etc, will require improved crystallinity of the mineral network. Researches in order to prepare textured crystalline materials are getting very active in this area and are presently carried out in mostly universities (U. of Santa Barbara, State Michigan University, Massachusetts Institute of Technology, University of Mulhouse). A new route to elaborate crystalline textured materials was developed at Rhodia and based on the self-assembly of nanoparticles. Some textured crystalline material developing hexagonal or lamellar were obtained using rare earth oxide nanoparticles. A new class of nanoparticles, amphiphilic nanoparticles, named Janus nanoparticles, was designed, processed and patented by Rhodia. A large range of Janus nanoparticles was defined. Uses of these Janus nanoparticles as new building blocks for textured crystalline materials will require a better understanding of the characteristics and self-assembly properties of theses new objects. This new class of amphiphilic nanoparticles should offer new opportunities for processing new structured materials. This project will involve various field of expertise: Colloidal Science, Physico chemistry of self assembly, Material processing,
