Abstract

A promising approach of designing mesostructured materials with novel physical behavior is based on combining unique optical and electronic properties of solid nanoparticles with long- range orientational ordering and facile electric switching. This lecture will describe how we practically realize molecular-colloidal composites formed via multi-scale self-assembly in dispersions of anisotropic nanoparticles into liquid crystal structures. Ranging from colloidal dispersions to aerogels, these composites are pre-engineered to exhibit novel plasmonic, electro- chromic, thermally insulating, photonic and other unusual physical properties controlled by low- voltage fields and light itself. The lecture will conclude with a discussion of a new breed of potential applications of these liquid crystal composites in smart windows and electro-optics.
