Cover Story: The formation of porous structures from polymer solutions at the surface in contact with solid surfaces via a thermally induced phase separation (TIPS) process was numerically investigated. When the compatibilities between the polymer-rich phase formed by the phase separation and the solid surface were high or low, surface porosity decreased. In contrast, for the solid surface with similar compatibilities with the polymer and solvent, high surface porosity was achieved. This indicates that the compatibility between the solid surface and polymer solution is important, and optimal compatibility results in high surface porosity. The knowledge obtained in this work could be useful in designing the coagulation bath component in the membrane preparation process by TIPS for achieving high surface porosity. View this paper.
