Research Abstract	コロイド結晶をモデルとして情報変換・伝達におけるシンクロナイゼーション効果の本性を明らかにする目的で、コロイド粒子の動的運動を顕微鏡観測により直接観察した。さらにこれまでの我々の先駆的な研究しか例のないコロイド結晶の粘弾性的測定から得られる情報と総合的に組み合わせ、コロイド結晶を分子シンクロナイゼーション材料としてとらえその特性解析を行った。具体的にはコロイド結晶の発現とそのキャラクタリゼーションを行い、電気光学効果発現の基礎となるコロイド単結晶のモルホロジーを明らかにした。電極付セルを試作し、動的粘弾性測定により電気光学効果の特性評価を行った。1.巨大コロイド結晶の発現とそのキャラクタリゼーシヨン:単分散ポリスチレンまたは単分散シリカ粒子を用い、水系・アルコール系で巨大コロイド単結晶を発現させた。定常光反射スペクトルによる測定で、結晶系の決定を行った。近接ビデオ撮影により、結晶の大きさと結晶構造を決定した。(2)光反射強度測定による電気光学効果の測定:電気光学効果測定用の電極付セルの試作を行った。製作したセルは平板透明電極型とブリッジ型の2個である。電場印加下の反射光強度の時間変化についてコロイド粒子の種類、粒径、粒子形状、コロイド結晶の大きさ、形状を変化させながら測定を行った。(3)静的・動的光散乱測定によるコロイド粒子の運動モード評価:光散乱法と反射スペクトル法とは、本質的には同種の運動モードをとらえるので、静的・動的光散乱測定を行いこの結果も比較検討した。静的構造因子、見かけの拡散係数を、コロイド粒子濃度を変化させながら測定した。(4)粒子運動解析装置・動的粘弾性測定装置による粒子の動的粘弾性特性解析:動的粘弾性測定装置により粒子系全体の運動特性を調査した。
