This department deals with smart coating processing based on nanoparticle processing, which leads to advanced manufacturing technology as well as safe,
security, environmental and energy issues. By making use of new properties of nanoparticles, nanoporous or multi-component films can be created without any heat assistance. Nano and microscale design of particles will lead to high reliability and functional coating films with various kinds of coating processes.
Smart coating on the surface of particles will make key materials for new areas such as Fuel Cells or DDS (Drug Delivery System).

Formation of Multi-layered Structure on Core Particle Surface by Nanoparticle Processing in Dry Phase: SEM image of multi-layered structure on core particle surface by nanoparticle processing in dry phase (left side). Surface layer is polymer film with nanospaces, and intermediate layer is shown by EPMA mapping image (Right side).
Fabrication of Both Cathode and Anode Nanostructure for SOFC by Wet Processing: LSM powder and Ni-YSZ composite powder were successfully processed. They were used for nanostructure control of both cathode and anode.
Fabrication of Cathode Particle with Gradient Composition for Li Ion Battery by Dry Processing: Nanoparticles as a shell were synthesized and coated on core particles by dry powder processing. The concentration-gradient cathode particles for Li ion battery were fabricated by calcination of the core@shell particles.
