Outline of Final Research Achievements

We have investigated a synthetic method for magnetic nanoparticles which are bonded and integrated (hereinafter referred to as magnetic nanocluster), and a colloidal dispersion system in which magnetic nanoclusters are dispersed as a magnetorheological (MR) fluid. Magnetite magnetic nanoclusters were successfully synthesized by the developed reductive hydrolysis method. They were also clarified to be exhibited superparamagnetic-like magnetic properties by controlling the structure of magnetic nanoclusters. Furthermore, it was revealed that the colloidal dispersion system of magnetite magnetic nanoclusters exhibited the MR effect, suggesting the possibility of soft-robotics application.

Academic Significance and Societal Importance of the Research Achievements

本研究ではマグネタイト磁性ナノクラスターのシンプルでスケーラブルな合成法を開発した。これはナノ粒子の構造体を自己組織的に構築するための方法論であり、他の金属酸化物ナノクラスターの合成および機能探索に応用できる可能性もある。磁性ナノクラスターが液中に分散した流体材料は磁場刺激(磁場強度)に応じて、流動性からゲル状の固体までそのレオロジー特性が大きく変化した(磁気粘性効果)。室温で等温可逆的に流動特性が大きく変化する材料は人間共存型ロボット等のソフト・ロボティックス分野に展開できるものと期待される。
