Description
薄膜の膜厚は、1〜1000nmであり、
支持膜が、感光性組成物からなる感光性組成物膜を露光及び現像して形成される、厚さ方向に貫通する複数の孔部を有する、膜厚1〜1000μmの多孔膜である、メンブレンフィルターに関する。
本発明にかかるメンブレンフィルターは、薄膜と、前記薄膜を支持する支持膜とが積層されたメンブレンフィルターである。薄膜の膜厚は1〜1000nmである。支持膜は、感光性組成物からなる感光性組成物膜を露光及び現像して形成される、厚さ方向に貫通する複数の孔部を有する、膜厚1〜1000μmの多孔膜である。以下、薄膜、及び支持膜について、厚さ方向に貫通する孔部を貫通孔とも記す。薄膜及び支持膜は、樹脂溶液や液状の感光性組成物の塗布によって容易に形成可能であるため、本発明にかかるメンブレンフィルターは大面積化が容易である。以下、薄膜及び支持膜について順に説明する。
薄膜の膜厚は、1〜1000nmである。薄膜の強度と、メンブレンフィルターの良好な透過性とを両立しやすいことから、薄膜の厚さは、5〜1000nmが好ましい。薄膜は極めて薄いため、貫通孔や空孔を有さない場合でも、気体や液体を構成する種々の分子を、薄膜を構成する材料の分子間に形成される空隙のサイズに応じて透過させる。
支持膜は、感光性組成物からなる感光性組成物膜を露光及び現像して形成される、厚さ方向に貫通する複数の孔部を有する、膜厚1〜1000μmの多孔膜である。支持膜の強度と、メンブレンフィルターの良好な透過性とを両立しやすいことから、支持膜の厚さは、5〜1000μmが好ましい。
メンブレンフィルターの製造方法は、それぞれ所定の構成を備える薄膜と支持膜とを積層できる方法であれば特に限定されない。以下、メンブレンフィルターの好ましい製造方法について、第一の方法、第二の方法、及び第三の方法について説明する。
本発明にかかるメンブレンフィルターの製造方法のうち、薄膜14が貫通孔を有さない場合の好ましい方法としては、基板10上に薄膜14を形成した後に、薄膜14上に感光性組成物の厚膜(以下、感光性組成物厚膜15とも記す)を形成し、形成された感光性組成物厚膜15に対して露光及び現像を行って支持膜19を形成する方法が挙げられる。この方法を、メンブレンフィルター21の好ましい製造方法のうちの第一の方法と称する。
本発明にかかるメンブレンフィルターの製造方法のうち、薄膜14が貫通孔を有さない場合の第一の方法と異なる好ましい方法としては、基板10上に形成された薄膜14を、薄膜14を備える基板10とは別の基板10上に形成された支持膜19の表面に接着する方法が挙げられる。この方法を、メンブレンフィルター21の好ましい製造方法のうちの第二の方法と称する。
本発明にかかるメンブレンフィルターの製造方法のうち、薄膜14が貫通孔を有する場合の好ましい方法としては、基板10上に形成された貫通孔を有する薄膜14を、薄膜14を備える基板10とは別の基板10上に形成された支持膜19の表面に接着する方法が挙げられる。この方法を、メンブレンフィルター21の好ましい製造方法のうちの第三の方法と称する。
以下、第一の方法の変形例について、図4を参照しながら説明する。第三の方法によれば、貫通孔を備える薄膜と、貫通孔を備える支持膜とが積層されたメンブレンフィルターを製造するために、2枚の基板が必要であった。しかし、第一の方法の変形例によれば、一枚の基板のみを用いて、貫通孔を備える薄膜と、貫通孔を備える支持膜とが積層されたメンブレンフィルターを製造することができる。
なお、薄膜14の貫通孔に充填された感光性組成物は、露光された感光性組成物厚膜15を現像液18により現像する際に、現像液18に溶解して除去される。このため、感光性組成物厚膜15を形成する際に、薄膜14中の貫通孔に、必ずしも感光性組成物が完全に充填される必要はない。
なお、本変形例においては、薄膜14の貫通孔に充填された感光性組成物が完全に露光されるように、感光性組成物厚膜15が位置選択的に露光される。そうすることで、露光された感光性組成物厚膜15を現像液18により現像する際に、薄膜14中の貫通孔に充填された感光性組成物が、感光性組成物厚膜15中に形成された露光部16とともに現像液18中に溶解する。
ガラス製の基板上に、水添型スチレン−イソプレン共重合体である下記構造の熱可塑性エラストマーをデカヒドロナフタリンに溶解させた溶液(固形分濃度10質量%)を塗布した後、90℃5分、及び120℃5分の条件でベークを行い、膜厚1.5μmの犠牲膜を形成した。
薄膜の膜厚を1500nmとすることの他は、実施例と同様にしてメンブレンフィルターを得た。得られたメンブレンフィルターについて、実施例と同様に、差圧0.05MPaを与えた場合の窒素流量を確認したところ、窒素流量は0ml/分であった。つまり、比較例のメンブレンフィルターは、差圧0.05MPaにおいて窒素を透過させなかった。
