    The "membrane" is a general term for a thin layered substance for isolation, of which the thickness can range from a few microns to a few millimeters. The "membrane" here refers specifically to materials with selective separation function, also known as separation membrane, through which one or several substances in the fluid can permeate while the other one or several substances cannot, thereby playing the role of separation, purification and concentration. The membrane is also defined as "a three-dimensional structure" internationally. "The size of one dimension in three dimensions is much smaller than the other two, and mass transfer can be realized due to various driving forces.” The membrane has two outstanding features: (1) The membrane is the interface between two phases, which is in contact with the fluids on both sides. (2) The membrane has selective permeability. As for the separation membrane, the external energy or chemical potential difference is the driving force, so that the different substances in the mixture can be separated via the selective permeation of the separation membrane to realize the processes of separating, purifying and concentrating.
