Outline of Final Research Achievements

A new nanocomposite that has a mesoporous structure with an ultrahigh porosity (up to ~97%) was developed from inorganic nanoparticles and organic polymer nanofibers. In contrast to conventional dense nanocomposites, surfaces of the embedded inorganic nanoparticles in the polymer matrix are still accessible from the ambient environment. The new nanocomposite shows surface chemical functions of the nanoparticles without being disturbed by the matrix either physically or optically.

Academic Significance and Societal Importance of the Research Achievements

従来の緻密なコンポジットの概念を覆し、超高空隙率を前提とした「空気のような」ナノコンポジットという新しい材料のカテゴリーを開拓した。また、メソポーラス構造のベースとなるナノファイバーの形成過程の解明を通じて、ナノ粒子やナノファイバーの空間秩序を精密に制御できる可能性を示し、今後のナノコンポジット材料の高機能化研究の基盤となる知見を構築した。
