我々はリオトロピック液晶であるC_<10>E_3/H_2Oを用い、そのスポンジ相(無秩序相)からのラメラ相(秩序相)の核形成キネティクスについて研究した。その結果特に低濃度の試料において、円盤状のラメラ核が変形して球状のオニオン構造を形成する、新たなオニオン相の自発的形成機構を発見した。これは界面エネルギーと変形の自由度が結合した、ソフトマターに特有の機構と考えられる。更に高濃度の試料では、強い非平衡状態下において、異方的で速い特有の枝形成・成長機構が見られた。発表では、セルに閉じ込められた状態における、セル表面での不均一核形成と表面から離れたパルク中での均一枝形成の競合も含めて報告する予定である。
