Description
架橋可能な親水性化剤を有する各種の膜の後処理を調査した。PVDF、Halar、及びPP膜を全て試験した。Halar膜については、MF(精密濾過)及びUF(限外濾過)膜を試験した。
TIPS膜
0から1重量%まで変化する割合で、標準的なTIPS PVDFまたはTIPS HalarドープにPVMEを添加した。TIPSの押出成形を連続法で操作した(所望であればバッチ法での使用を禁ずるものは何もないが)。PVDFについて、PVMEをGTAとジエチレングリコール、トリエチレングリコール、または1,4-ブタンジオールとの溶媒/非溶媒混合物に溶解した。Halarについて、PVMEを単純にGTAに溶解した。PVMEはGTAに非常に可溶性であるが、ジエチレングリコール、トリエチレングリコール、及び1,4-ブタンジオールのようなより極性の化合物には不溶性である。
以下の表6に示された組成物で3種のドープを調製した。2種の異なる割合のPVME(0.1重量%及び2.5重量%)を、代替的な添加剤としてポリ(ビニルピロリドン-ビニルアセタート)(S630)を含むDIPS PVDFと比較した。これらの繊維は全て同一の態様で押出成形され、その結果が以下の比較されている。
