Colloidal Superstructures and Porous Materials
We are mainly interested in the shape-controlled synthesis and surface modification of colloidal particles for assembling them into colloidal superstructures which can be extremely useful for photonic crystals, photonic glasses, metamaterials, colloidal transistor, sensors, lithium-ion battery electrodes. Such colloidal structures can be used as templates for porous materials. We have been working on hierarchically structured porous particles or films by introducing surfactants as additional templates, which have been implemented as separators or electrodes in lithium-ion battery, light scatterer for solar cells, substrates for colorimetric sensor or bioadhesives for bioloigical tissues. Recently, we have started developing polymeric nanoporous materials for developing solid electrolytes for lithium ion battery.
