Materials Technology
Development of new materials is a core technology that has walked together with human history and technology movement. Studies on modern technology of new materials is focusing on the extraction of synergistic properties through a fusion of individual materials, which requires a profound understanding on the chemistry as a fundamental of the material and the chemical engineering as a toolkit for the realization. Our research group is fully constructing systematic resources for materials design, synthesis, characterization and manipulation, particularly based on the specialized organic and polymeric materials, from which we are directing the development of versatile materials for biomedical, electronic and industrial applications. Furthermore, under the academic banner of °?sustainable growth°Ø for the next generation, we are currently emphasizing studies on environmentally benign and low-energy consuming materials and processing.

Polymeric thin Films Self-assembly and interfacial Engineering
To fabricate the functionalized polymeric thin films, layer-by-layer self-assembly of polyelectrolyte multilayers is employed, in which the molecular interactions can be elaborately manipulated for creating various physicochemical properites or unique nanostructures. In addition, our group has developed a novel technique of generating complexly wrinkled micro/nanostructures based on the understanding of thin film instability and mechanical deformation, whereby the accumulated stress in hybridized thin films can be harnessed into creating useful micro/nanostructures.

Unconventional Nanopattering and Nano-Architecting
Instead of resorting to high-cost process demanding photolithographic method, we utilize the unconventional nanopatterning strategies, such as capillary force lithography, rigiflex lithography, and spontaneous 3D structuring method, such that the well-defined and hightly integrated nanopatterns can be demonstrated in a large scale with low cost. Combined with further processing of selective functionalization, these nanopatterns rae developed for bio and chemical sensors and microfluidic applications. Moreover, 3D patterned nanostructures are utilized for the next-generation nano-and ultra-filtration membrane applications.

Templated Electorode Design with Polymer/Inorganic Hybrid Materials
Convenional nanomaterials of nanoparticles or nanowires exhibit a limitation in a high-density integration or a large-scale demonstration due to their difficulties in surface functionalization and spatial manipulation. To overcome this drawback, we propose a technique of a templated synthesis for creating highly integrated nanoparticle or nanowire 3D structures. Toward this goal, a self-assembly process between polymeric and inorganic species in solution phase is exploited to develop the 3D integrated hierarchical structures, wherein the individual characteristics of nanomaterials are efficiently extended to bulk-scale. Therefore, applications associated with high capacity energy devices can be readily developed ont eh basis of this templating strategy, such as for electrodes of Li-ion batteries or dye-sensitized solar cells and supercapacitors.
