Water Vapor Permeability of Composite Membrane
Kobunshi Kagaku, 1971 高分子複合皮膜の透過性に対する成分皮膜の寄与を解明するために, 親水性高分子たるセロハンおよび疎水性高分子であるポリエチレンフィルムを用い, まずそれぞれ単一成分の水蒸気透過挙動を調べ, 次にそれらをはり合わせた複合皮膜について, 透過方向をかえた実験を含めて水蒸気透過性を検討した。セロハン単独皮膜の透過係数P, 拡散係数Dはともに入側の水蒸気圧力とともに増加するが, これにはフィルム中の水蒸気濃度の増加による自由容積の増大に伴う拡散係数の増加と, 分子の会合 (クラスタリンダ) による拡散係数の低下が組み合わさって作用する。ポリエチレン単独皮膜のPおよびDは, 水蒸気圧力によってほとんど変化しない。セロハン-ポリエチレン複合皮膜で, セロハン側から水蒸気を透過せしめる場合は, 相対蒸気圧0 ...

Organophosphorus Polyurethane Ionomers as Water Vapor Permeable and Pervaporation Membranes [PDF]
Polymers, 2021 Organophosphorus polyurethane ionomers (AEPA-PU) based on aminoethers of ortho-phosphoric acid (AEPA) were obtained and studied as pervaporation membrane materials for separating isopropanol/water mixtures. The regularities of the change in the water vapor permeability of AEPA-PU were also investigated.
