Abstract

It is now well understood that the nanocomposite concept is very promising to significantly improve mechanical and thermal properties of engineering ceramics. And concentrated researches on nanocomposites gave us new strategy to develop the unique materials with multi functionality.  Thus, our research was focused on the multifunctional ceramic materials, and various kinds of new multifunctional ceramic materials were successfully developed, which showed the improved strength and toughness together with new functions such as machinability like metals, electrical conductivity and stress & fracture sensing function and so on.  And some of them were already industrialized in last 7 years.  Another important finding in the nanocomposite research was that its concept was also applicable for metasl and polymers, and new materials successfully developed: for example, a polymer based nanocomposite with a new sensing function like human’s finger tip which was already industrialized as special sensors of intelligent robot named as AIBO, personal computers, hand phones and automobiles. 

Research on new materials, named as “lattice and molecular level composite”, has been also made in our groups set in Osaka and Nagaoka.  And various materials with new structures and unique functions have been developed in the last 3 years.

In the presentation, the nanocomposite concept developed by present author in 1986, the processing and the structure-property revolution by this concept will be first reviewed briefly.  And then I will mainly discuss recent results on multifunctional materials, in special, mechanically and electrically multifunctionalized nanocomposites in ceramic and polymer materials.  In final, our new materials design concept on molecular/cluster/lattice level composites and some new results on them will be presented and discussed.
