Membrane performance depends to a great extent on the porous structure. Narrow pore size distributions produce sharp separations. Membrane pore morphology has an effect on the hydraulic resistance and thus on the energy requirements for filtration. Methods that allow for detailed control of these parameters at the nanometric scale are highly desirable. Traditional methods for the fabrication of porous membranes are limited in the variety and definition of structures that can be obtained. In this work, polymeric porous membranes with 3D ordered structure were fabricated from templates made from silica particles.
