Description
本工程は、製膜原液を基材上に膜状に塗布する工程である。塗布方法の具体例としては例えば、製膜原液を基材の表面にキャスト厚調整可能なアプリケータを用いて押し広げる方法もしくは塗り広げる方法、またはT−ダイから製造原液を吐出する方法などが挙げられる。
本工程は、上記製膜原液供給工程後の基材を、水を含有する凝固浴に浸漬させる工程であり、より具体的には、前記製膜原液が塗布された基材を凝固浴に浸漬させて、前記非水溶性第1成分ポリマーを該基材上に析出させる工程である。
本工程は、上記凝固浴浸漬工程後の基材を、水浴に浸漬させ溶剤成分および/または前記水溶性第2成分ポリマーを除去する工程である。より具体的には、前記非水溶性第1成分ポリマーが析出されて形成される膜(以下、単に「第1成分ポリマーからなる膜」とも称する)を、水浴中に好ましくは10〜1000分間、より好ましくは15〜60分間浸漬させることで、前記溶剤成分および/または前記水溶性第2成分ポリマー等を抽出除去する工程である。
本工程は、上記洗浄工程後の第1成分ポリマーからなる膜を乾燥させる工程である。より具体的には、自然乾燥や電気オーブン等を用いて、好ましくは30〜100℃、より好ましくは40〜80℃の温度で、好ましくは1分〜24時間、より好ましくは1分〜2時間乾燥させる方法が例示される。
上記で得られた多孔質膜を用い、次の実験を行った。各多孔質膜に、試薬として、グルコースオキシターゼ(GOD)、ペルオキシターゼ(POD)および4−アミノアンチピリン、N−エチル−N−(2−ヒドロキシ−3−スルホプロピル)−m−トルイジン(TOOS)を、親水化剤としてトライトン(登録商標)X−100を、それぞれ担持させた。担持方法としては、上記試薬および親水化剤を溶解させたリン酸緩衝液に、得られた各多孔質膜を浸漬させ、該試薬および該親水化剤がコートされた後に乾燥する方法を採用した。
Claims (1)
- 少なくとも1種のポリマーが非溶出相を、他のポリマーが溶媒に溶出される溶出相を形成した後、溶媒に浸漬させることにより多孔質膜を形成する多孔質膜の製造方法であって、
前記非溶出相を形成する非水溶性第1成分ポリマーと、前記溶出相を形成しうる重量平均分子量の±4%の範囲内にある重量平均分子量を有する水溶性第2成分ポリマーと、を含む製膜原液を基材上に膜状に広げる製膜原液供給工程と、
該製膜原液供給工程後の基材を凝固浴に浸漬させる凝固浴浸漬工程と、
該凝固浴浸漬工程後の基材を水浴中で溶剤成分および水溶性添加剤成分の少なくとも一方を除去する洗浄工程と、
該洗浄工程後の基材を乾燥させる工程と、
を含み、
前記非水溶性第1成分ポリマーは、ポリエーテルスルホンであり、
前記水溶性第2成分ポリマーは、ゲル浸透クロマトグラフィによるポリエチレングリコール/ポリエチレンオキサイド換算の値で測定した重量平均分子量が、30,000±4%の範囲内にあるポリビニルピロリドンであり、
前記多孔質膜は、血中のグルコース量に応じて呈色する試薬を担持する血糖値測定用の多孔質膜として用いられる、多孔質膜の製造方法。
