Abstract: PURPOSE: A super water-repellent organic/inorganic composite membrane with excellent phase separation capability is provided. CONSTITUTION: The super water-repellent organic/inorganic composite membrane is characterized in that azo-based silane chloride initiator serving as an intermediating layer is formed on a porous inorganic support, and a skin layer formed of fluorine-based monomer copolymer is formed on the intermediating layer, wherein the initiator is chemically bonded to the surface of the porous inorganic support and the fluorine-based monomer is chemically bonded to polymer brushes at moiety of radical of initiator. According to the present invention, the fluorine-based monomer copolymer is represented as follows: CF2=CF2, CH2=CF2, XCnF2nCH2OCOCR1=CH2, XCnF2nSO2NR2(CH2)mOCOCR1=CH2, XCnF2nCH2CH(OH)(CH2)mOCOCR1=CH2, XCnF2n(CH2)mOCOCR1=CH2 where R1 is hydrogen atom or methyl group; R2 is methyl group, ethyl group or propyl group; X is hydrogen atom, fluorine atom or chlorine atom; m is an integer of 2 to 6; n is an integer of 3 to 21.
