asymmetric membranes

Asymmetric membranes are materials with a layered structure, featuring a thin, dense outer layer and a thicker, more porous inner layer. This design allows the membrane to effectively filter or separate substances: the dense surface catches small particles, while the porous core provides support and flow capacity. Such membranes are commonly used in water treatment, medical dialysis, and gas separation, where precise filtering and durability are essential. The asymmetry optimizes performance by balancing selectivity with mechanical strength, making the membrane both efficient and long-lasting.
