| description | A method for manufacturing a porous polyketone membrane according to the present invention comprises the steps of: mixing polyketone and a diluent at a temperature of 190-270°C to manufacture a dope solution; applying the manufactured dope solution on a support, rapidly solidifying the solution using an aqueous coolant containing at least one selected from a group consisting of water and an organic solvent at 4-70°C, and manufacturing a porous polyketone membrane by a heat-induced separation method; and extracting and removing the diluent from the porous membrane. According to the present invention, a porous polyketone membrane excellent in chemical resistance and heat resistance can be manufactured.
본 발명에 따른 폴리케톤 다공성막의 제조방법은 폴리케톤 및 희석제를 190 내지 270℃의 온도에서 혼합하여 도프(dope) 용액을 제조하는 단계; 제조된 상기 도프 용액을 지지체 상에 도포하고 4 내지 70℃의, 물 및 유기용매로 이루어진 군에서 선택되는 1 이상을 포함하는 수성 냉매를 이용하여 급속 고형화하여 열유도상분리법으로 폴리케톤 다공성막을 제조하는 단계; 및 상기 다공성막으로부터 희석제를 추출하여 제거하는 단계;를 포함하는 것을 특징으로 한다. |
