Research Abstract

本年度は東京工業大学、ソウル大学共に以下に述ベる様に7人で90報を越える論文を発表し、大いに業績を上げることができた。
1 ソフト溶液プロセスによる高機能複合酸化物薄膜
我々が開発している溶液電気化学あるいは水熱電気化学法によりシーライト型AMO_4、ペロブスカイト型ABO_3さらにリチウム塩LiMO_2などの多くの複合酸化物の結晶性膜の低温直接作製に成功している。
2 錯体重合法による高機能セラミックス粉体
我々の提案に基づく本法の応用は広く、多くの超電導酸化物のほか光触媒、さらにはジルコニアなどのイオン導電材料や高強度セラミックスにも適用できた。
3 高機能複合酸化物の材料設計
組成と構造のみならず、電子構造、イオン構造を考慮することにより高度なイオン導電材料、超伝導材料、光触媒材料などを得ることに成功している。
4 無機/有機ハイブリッド材料の設計と作製
溶液からのインターカレーション反応を利用して、超伝導材料、イオン導電材料、触媒、吸着剤などの特性を示す無機/有機ハイブリッド材料の開発に成功している。
5 ナノ複合材の作製とその評価
SiO_2,TiO_2のナノ微粒子と有機高分子との複合化による高機能触媒、イオン導電体などが作製できることを見出している。
これらに関し相互の共同研究の成果も十数報に上る。
