The thermally induced phase separation(TIPS) method offers higher reproducibility with lower tendency for defect formation and narrower pore size distribution, rendering the method more suitable for microfiltration(MF) and ultrafiltration(UF) applications. PVDF is widely used in membrane technology due to their excellent chemical resistance and strong mechanical properties. In case of MF and UF applications, the stretching method has been applied for increasing the performance of membrane by extending pore size. In this work, the effects of dope and bore flow rates and dope composition on the tensile strength of membranes was investigated. A design of experiment(DOE) analysis was used to understand the effects of the stretching parameters such as temperature, stretching ratio and holding time on the membrane performance.
