Over the past dozen years there has been a significant effort to create new assemblies of colloid crystals with increasingly complex structures. In this presentation, I will introduce novel method to fabricate various colloids using polymerizable liquid crystal (PLC) shells and droplets. Since liquid crystals (LCs) can have various self-assembled structures depending on their phases, size, thickness, surface anchoring and elasticity, a rich of topologies can be formed in spherical confinements such as shell or bulk drop by coding particular LC fields. Here, I have shown various PLC colloids by using the topologies as skeletal for topographical evolution through two steps, polymerization and buckling by volume contraction. The mechanism of buckling and reversible behaviors by swelling and de-swelling were studied and the topographical structures were observed using polarized optical microscopy (POM) and scanning electron microscopy (SEM). |
