Abstract

有機溶媒、ポリマー、及び酸化防止剤を含む添加剤液を混合して、高分子溶液（１１）をつくる。高分子溶液（１１）を、走行するエンドレスバンド（１１８）にキャストする。エンドレスバンド（１１８）にキャストされた高分子溶液（１１）は、キャスト膜（２２）となる。結露により、第１エリア（１１１）を通過するキャスト膜（２２）上に水滴を形成する。第２エリア（１１２）を通過するキャスト膜（２２）上の水滴が成長するとともに、有機溶媒が蒸発する。高分子溶液（１１）の調製から４８時間が経過する前に、十分乾燥したキャスト膜（２２）を第３エリア（１１３）へ送る。第３エリア（１１３）を通過するキャスト膜（２２）上の水滴が蒸発する。剥取ローラ（１５７）により、第３エリア（１１３）を経たキャスト膜（２２）は、エンドレスバンド（１１８）から酸化防止剤を含む多孔フイルム（１７）として剥ぎ取られる。
