METHOD FOR PREDICTING QUALITY OF POLYMER MEMBRANE USING BY MEASURING SOLIDIFICATION RATE DEVICE FOR PREDICTING SAME AND METHOD FOR MANUFACTURING POLYMER MEMBRANE

The present application relates to a method for predicting the quality of a polymer membrane and an apparatus for predicting the quality of a polymer membrane using a method for measuring the coagulation rate of a dope solution comprising a step of measuring with a rheometer. The present invention comprises steps of: disposing a laminate of coating layers; positioning a geometry of the rheometer to be in contact with part or all of a surface of the coating layer opposite to the surface opposite to a second porous support; advancing the coagulation of the coating layer by adding a non-solvent to the inside of a bath; and measuring the rate of change of a storage modulus of the coating layer with time by the rheometer while the coating layer is solidified, thereby measuring the solidification rate of the dope solution. An object of the present invention is to provide a method capable of measuring the coagulation rate of an efficient dope solution for optimizing the microstructure of a porous polymer membrane. 본 출원은 레오미터로 측정하는 단계를 포함하는 도프 용액의 응고 속도를 측정하는 방법을 이용하는 것인 고분자 분리막의 품질 예측 방법 및 고분자 분리막의 품질 예측 장치에 관한 것이다.
