| Research Abstract |
In this research project, we have developed many kind of intermaterials with excellent multi-functionality by controlling materials structure in atomic, molecular and nano-scales. followed results have been obtained.
(1) New class of ceramics in Li-Nb-Ti-O was developed. This material has layer-by-layer superlattice, and we have succeeded to control its distance. Based on the anisotropic structure, tin-films and self-organized composite crystal consisted from oriented, rod-like precipitate within the superstructured single crystals.
(2) Properties of Na-Co-O thermoelectric ceramics have been improved by controlling the chemical compositions. Sinterability and Figure-of-merit of the materials was enhanced by doping small amount of oxides.
(3) Electric functionalization of insulating structure ceramics such as silicon nitride, zirconia, and so on have been developed by introducing 3-dimensional continuous conductive network into ceramics. As the results ionic and electron conductive ceramics with wide variety of conductivity have been developed.
(4) Pressure sensor consisted from soft-organic materials and inorganic conductive particles and strengthening nano-sized ceramic fillers have been developed. These nanosensor can detect from low to high load (pressure) by deformation. Also bio-compatible organic-inorganic hybrid materials have been developed, which exhibited excellent mechanical properties, chemical stability and bio-compatibility.
