Title (EN) LAYERED SEMIPERMEABLE MEMBRANE
(FR) MEMBRANE SEMI-PERMÉABLE STRATIFIÉE
(JA) 積層半透膜
Abstract:
(EN) The present invention relates to a layered semipermeable membrane satisfying the conditions below. (A) The maximum peak intensity between 3700 and 2900 cm-1 is 0.08 or greater in the difference spectrum between an IR spectrum measured at 25°C and 97% relative humidity and an IR spectrum measured at 25°C and 3% relative humidity. (B) The peak top wavenumber between 3700 and 2900 cm-1 of the aforementioned difference spectrum is 3400 cm-1 to 3550 cm-1. (C) The N1s peak has a maximum value at 401 eV or greater in X-ray photoelectron spectroscopy in which X-rays are radiated to a coat layer.
(FR) La présente invention concerne une membrane semi-perméable stratifiée satisfaisant aux conditions ci-dessous. (A) L’intensité de pic maximale entre 3700 et 2900 cm-1 est de 0,08 ou plus dans le spectre de différence entre un spectre IR mesuré à 25 °C et 97 % d’humidité relative et un spectre IR mesuré à 25 °C et 3 % d’humidité relative. (B) Le nombre d’onde maximal de pic entre 3700 et 2900 cm-1 du spectre de différence mentionné ci-dessus est de 3400 cm-1 à 3550 cm-1. (C) Le pic N1s a une valeur maximale à 401 eV ou plus en spectroscopie photoélectronique à rayons X dans laquelle des rayons X sont appliqués à une couche de revêtement.
(JA) 本発明は、下記条件を満たす積層半透膜に関する。(A)25℃、相対湿度97%で測定されるIRスペクトルと、25℃、相対湿度3%で測定されるIRスペクトルとの差スペクトルにおいて、3700~2900cm-1間の最大ピークの強度が0.08以上である。(B)前記差スペクトルの3700~2900cm-1間のピークトップ波数が3400cm-1以上かつ3550cm-1以下である。(C)前記コート層にX線を照射するX線光電子分光測定において、N1sのピークが401eV以上に極大値を持つ。
