This A brief introduction to membrane characterization is also given, which includes membrane porosity and pore size distribution characterization, membrane physical and chemical uction pores (macrovoids)The composition of polymer solution and the methods of membrane preparation determine the solidification process of membrane. (19) During the phase inversion process in a water bath, the PVDF diffuses out from the catalyst mixture and precipitates on the cathode surface, forming a thin but dense hydrophobic PVDF Institute on Membrane Technology, ITM-CNR, c/o University of Calabri, Rende, CS, Italy. The formation of membrane structure prepared via non-solvent induced liquid or dissolved phase forms the membrane pores and the solid phase the rigid membrane structure. This is a very versatile technique allowing all kind of morphologies to be obtained. Search for more papers by this author Green Chemistry and Environmental Biotechnology, University of Science and Technology, Daejeon, Korea. Thermogelation is readily applied for the preparation of glass and metalmembranes and the extrusion of microporous polyethylene or polypropylene tubes now are widely used in cross-flow microfiltration The phase inversion process occurs at room temperature, making membrane production simple and flexible, allowing large-scale production of low-cost membranes. In this paper, flat sheet polysulfone (PSF) membrane and polysulfone/montmorillonite (PSF/MMT) mixed matrix membranes with different MMT contents were prepared by dry Phase inversion processes, in which a polymer is transformed from a thin solution film into a solid matrix upon exposure to another gas/liquid phase or a temperature change, Phase inversion Most commercially available membranes are obtained by phase inversion.
