It is a functional semi-permeable membrane that allows solvent molecules or certain low molecular weight solutes or low-priced ions to pass through. It is a special and promising type of separation membrane. It is named because it can trap substances in a size of about nanometers. Its molecular weight is about 150-500, and its ability to trap dissolved salts is 2-.
