Description
本願は、「支持されていない多領域微孔性膜」の名称で2001年8月7日にセール(Sale)他により出願された米国特許出願第09/923,640号の一部継続出願であり、この出願は「支持されていない多領域微孔性膜」の名称で2000年8月7日にセール(Sale)他により出願された米国特許仮出願第60/223,359号の一部継続出願でありこの開示を本開示と矛盾しない範囲で参考としてここに取り込む。
本開示は、異なるが制御された二つ以上の膜孔径を有する、連続した支持されていない微孔性膜及び同膜の作成方法と使用方法に関し、特に、第一のドープと少なくとももう一つの付加ドープを急冷する前に直接重ねて付与することによって作成する支持されていない微孔性膜に関し、また、このような膜を製造する装置及び作製する方法に関する。
微孔性転相膜は業界では周知である。微孔性転相膜は、一つの表面からもう一つの表面へ延在する微孔性の相互連結路を含む多孔性の個体である。これらの連結路は、ろ過された液体が必ず通過する蛇行したトンネルあるいは通路を備える。微孔性転相膜を通過する液体に含まれる粒子は、ろ過を行なう膜構造体上に、あるいは膜構造体内に取り込まれる。膜孔より大きい液体中の粒子は、膜への進入が阻止されるか、または膜孔内に取り込まれ、膜孔より小さい一部の粒子も、膜孔蛇行通路内の膜孔構造体内に取り込まれるか、または吸収される。液体及び膜孔より小さい他の粒子は通過する。微孔性転相膜は、約0.01ミクロン以下の粒子から10.0ミクロン以上の粒子までの範囲を留めることができる。
本開示は、支持されていない(補強用または支持用の一体の膜孔支持体を有さない)多層微孔性膜、装置、及び製造方法を対象にする。この支持されていない膜では、現在好ましくは、各々が異なるが制御された膜孔径を有する複数(二層以上)で別々の層が実質的に同時に形成され得る。また、この支持されていない膜は、現在好ましくは、各々が異なるが制御された膜孔径を有する複数(二層以上)で別々の層からなり、膜孔径の局所的な非対称分布を示さずに各々の層間の界面において膜孔径がはっきりと変化しているので、図16a及び16cに表し、図12に実証され、以下に明確にするように、得られる膜は、タイプIのフォワードフローバブルポイント(FFBP)応答曲線を示す。
ここに開示するように、微孔性膜及びその生成方法は、図16a〜図16dに示すとおり、FFBP曲線によって特徴づけることもできる。親出願に含まれる実験を検討した結果、多層膜には、SEM分析から多層に見える膜だとしても、以下に述べる従来技術による方法で生成すると非対称度を示すものがあることを我々は発見した。しかし、本開示から明らかなように、生成物及び開示する多層膜を生成する方法は、この非対称を解消する。
親出願における当初は、PVDFポリマーから、多層で支持されていない微孔性膜を事後計量の流延方法(ナイフ流延)により生成することの実現性を確認するために、以下の実験を実施した。しかし、当初の結果を更に検討したところ、以下の実験が、PVDFポリマーと、元来評価していなかった事後計量の流延方法(ナイフ流延)によって作成した、多層で支持されていない単一の微孔性膜の特性を明らかにすることがわかった。
次の実験には、以下の成分を採用した。
PVDF(カイナー761)15%、IPA(2−プロパノールACS試薬)15%、及びNMP(1−メチル2ピロリジノンACS試薬)70%で総重量200グラムの混合物を磁石攪拌棒付き広口瓶内に混合して密閉し、水がジャケット内を所定温度で循環するジャケット付きビーカー内に浸漬した。混合には磁石攪拌器を用いた。構成物質を溶液にするため、得られたドープを目標温度(Tmax)より低い約10〜15℃の間まで加熱した。
以下の実験は、ナイロンを用いた多層で支持されていない微孔性膜生成の実現性を確認するために行なった。
次に続く実験には、以下の成分を採用した。
ドープの作製:
米国特許第4,707,265号明細書の例1に説明される方法を用いて、ナイロン・ドープを作製する。これらのドープは、ナイロン66(ソルーシアビディン(R)66Z)ポリマーを約16.0重量パーセント使用して生成する。
幾何学的対称及び膜孔径対称であり、支持されていない二層または三層膜で、それぞれの膜が独自の膜孔構造を有する膜は、以下のように作製する。
