An object of the present invention is to control the pore diameter of a separation filtration membrane according to the size of an object to be separated by freely controlling the pore diameter of the same polymer membrane. Furthermore, the development of a method for producing functional polymer membranes in which low-functional molecules are confined inside the polymer membrane by the pore size control method. When forming a collodion film, a water molecule is added in the form of an ethanol solution to form a film, and then removed, and a pore diameter expansion control method is formed. The hole diameter reduction control method by this. A method for producing a functional polymer film in which salicylic acid and cobalt chloride are added to form a collodion film and the cobalt chloride is confined in the pore diameter of the collodion film by using this pore size reduction control method. As a result, a functional polymer membrane in which cobalt chloride is confined in a new pore size of a collodion membrane composed of polymer pyroxylin and salicylic acid. [Selection] Figure 12 |
