    Abstract: A fluorine resin membrane is made hydrophilic to a prescribed depth in the direction of thickness thereof to produce an asymmetrical membrane having a hydrophilic portion and a hydrophobic portion. An enzyme is immobilized in the hydrophilic portion of the membrane to obtain a membrane having a function of enzymatic reaction and a function of selective gas permeation. The hydrophilic portion is formed by causing a perfluoroalkyl surface active agent to penetrate the prescribed depth that is to be hydrophilic.

    Abstract translation: 使氟树脂膜在其厚度方向上具有规定深度的亲水性,以产生具有亲水部分和疏水部分的不对称膜。 将酶固定在膜的亲水部分中以获得具有酶反应功能的膜和选择性气体渗透的功能。 亲水部分是通过使全氟烷基表面活性剂渗透到要亲水的规定深度而形成的。
