In this presentation, we will introduce novel approach to fabricate various shape and surfaces of shells using liquid crystals (LCs) as scaffold for the polymeric network. Since 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, we have shown various LC polymeric 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). |
