While nanoparticles and polymers are widely used materials in industrial/daily products, it can exhibit unique properties when they are combined. Our research group is interested in understanding of particle-polymer interactions and controlling the structures to produce
desired properties in complex nanoparticle-polymer composites. Upon the deep understanding of structural behavior of polymer composite materials, versatile thin film and novel 3-D nanostructures can be created; block copolymer related composite is explored.
