Research Abstract	研究の初年度として、以下の微細構造形成過程とその機能を重点的に研究した。1.界面活性剤から形成される分子集合体と機能: W/O-マイクロエマルション(ME)のパーコレション挙動、水溶性高分子と脂質分子MEとの相互作用、ミセルからベシクルへの転移挙動を明かとした。これらを基礎に、孤立性の高いMEを用いた液状固定化酵素の提案、タンパク質を組み込んだベシクルの機能、ベシクル/ミセル間の転移点近傍における組織の不斉識別機能と分子認識機能、ME構造と半導体超微粒子形成との関係などを明らかとした。2.高分子系における秩序形成の動的過程と構造の機能:高分子溶液内での溶媒除去誘起型・反応誘起型の構造形成過程や分岐架橋を伴う高分子ゲル形成過程と構造制御を実験的、理論的に明かとした。また、ポリイミドの薄膜構造制御と気体分子透過特性や親水性高分子膜構造と生理活性物質の分離能との関連、シリコンアルコキシド重合系粒子形成過程のモデル化と粒子径分布の制御指針、微粒子表面への高分子皮膜形成過程などについて多くの知見を得た。3.複合材料における秩序形成過程と構造の機能:結晶粒界の超伝導接合による超伝導クラスターの形成過程をバ-コレション過程の考え方から解明し、また、鍍金表面での析出結晶構造・形態を実験的に明かとした。さらに、水溶液中のタンパク質の乾燥過程とタンパク質の安定性との関係を、添加する糖のアモルファス構造に焦点をあてて明かとした。4,微粒子系における秩序形成過程:粒子系の構造形成の基礎となる粒子界面構造と粒子間相互作用を原子力顕微鏡を用いて実験的に解明した。また、電気粘性流体を対象に、電場を付加したときの粒子構造形成過程に対する計算機実験手法の有用性、ポリスチレン/溶媒系に於ける溶媒の乾燥過程とマイクロカプセル形成との関連につき検討した。以上の構造形成過程を横断的に眺める方法論についても検討を加えた。
