Abstract

高分子化合物と両親媒性化合物とが溶媒に溶解した溶液を支持体（２１）上にキャストしてキャスト膜（２２）を形成する。キャスト膜（２２）に含有する溶媒（２３）を蒸発させながら、キャスト膜（２２）の露出面（２２ａ）に水滴（２５）を形成する。溶媒（２３）を蒸発させながら、水滴（２５）を成長させる。水滴（２５）はキャスト膜（２２）の中に入り込む。キャスト膜（２２）に入り込んでいた水滴（２５）を蒸発させる。水滴（２５）の蒸発により、固形化したキャスト膜（２２）に孔が形成される。水滴或いは溶媒の表面張力や、水滴と溶媒との界面張力が、水滴（２５）の形成プロセスに大きな影響を与える。溶媒として親水性液体を含む溶媒を用いることにより、水滴（２５）を露出面（２２ａ）上に均一に形成することができ、寸法のばらつきが抑制された均一な孔を備える多孔質フイルムを容易に製造することができる。
