In this study, a nonsolvent thermally-induced phase separation (NTIPS) method was first proposed to fabricate hydrophilically-modified poly(vinylidene fluoride) (PVDF) membranes to overcome the drawbacks of conventional thermally-induced phase separation (TIPS) and nonsolvent-induced phase separation (NIPS) methods. Hydrophilically-modified PVDF membranes were successfully prepared by blending ...
Mesoporous polyacrylonitrile (PAN) monolith has been fabricated by a template-free approach using the unique affinity of PAN towards a water/dimethyl sulfoxide (DMSO) mixture. A newly developed Thermally Induced Phase Separation Technique (TIPS) has been used to obtain the polymer monoliths and their microstructures have been controlled by optimizing the concentration and cooling temperature.
In high-viscosity polymer solutions and blends, temperature variations during the quench process of thermally-induced phase separation (TIPS) influence dynamics thermodynamics separation. Hence, this study aims to investigate impact on morphology formation TIPS process. First, temporal is investigated by coupling a transient heat conduction model Cahn–Hilliard equation, results are compared wit...
