Abstract:
(EN) The present invention pertains to a composite semipermeable membrane comprising a support film including a substrate and a porous support layer, and a separation functional layer disposed on the porous support layer, said separation functional layer containing a crosslinked polyamide and a hydrophilic polymer that is a polymerized product of a monomer having an ethylenically-unsaturated group, and the ratio (the O/N ratio) of the atomic number of oxygen atoms to the atomic number of nitrogen atoms on the surface of the separation functional layer, measured by an X-ray photoelectron spectroscopy, is 1.5 or more and 10 or less, and the standard deviation of the ratio is 0.15 or more.
(FR) La présente invention concerne une membrane composite semi-perméable comprenant un film de support comprenant un substrat et une couche de support poreuse, et une couche fonctionnelle de séparation disposée sur la couche de support poreuse, ladite couche fonctionnelle de séparation contenant un polyamide réticulé et un polymère hydrophile qui est un produit polymérisé d'un monomère ayant un groupe éthyléniquement insaturé, et le rapport (rapport O/N) du nombre atomique d'atomes d'oxygène au nombre atomique d'atomes d'azote sur la surface de la couche fonctionnelle de séparation, mesuré par spectroscopie photoélectronique aux rayons X, est de 1,5 ou plus et de 10 ou moins, et l'écart type du rapport est de 0,15 ou plus.
(JA) 本発明は、基材及び多孔性支持層を含む支持膜と、前記多孔性支持層上に設けられた分離機能層からなる複合半透膜であって、前記分離機能層が、架橋ポリアミドと、エチレン性不飽和基を有するモノマーの重合体である親水性高分子とを含み、前記分離機能層表面の、X線光電子分光法により測定された窒素原子の原子数に対する酸素原子の原子数の比(O/N比)が1.5以上10以下かつ、前記比の標準偏差が0.15以上である、複合半透膜に関する。
