Summary: The review discusses eight physical methods for the fabrication of GO membranes, categorizing them based on batch-unit or continuous production into five small-scale (vacuum filtration, pressure-assisted filtration, spin coating, dip coating, drop-casting) and three large-scale (spray coating, bar/doctor blade coating, slot die coating) approaches. Large-scale methods offer the advantage of continuous production which is not limited by equipment dimensions but rather material availability, while small-scale methods are restricted by the size of the fabrication device.

Summary: PVDF mixed matrix membranes (MMMs) were prepared by combining PVDF with Ag@ZIF-8 using a one-pot microemulsion strategy, aiming to enhance the separation performance and anti-fouling property of PVDF ultrafiltration membranes. Ag and ZIF-8 were generated in one micelle during the formation of composites and then blended with PVDF to construct MMMs. The well-distributed Ag@ZIF-8 in PVDF matrix improved the permeation, flux recovery rate, and dye retention of MMMs from high-salinity wastewater.
