Fouling release membrane is a novel kind of membrane that has the chemical structure and main feature of nonpolar low surface energy microdomains and hydrophilic domains, inhibiting the nonspecific adsorption of a variety of foulants. The low surface energy microdomains on the membrane surface, which can be constructed with silicone- and fluorine-based polymers, are used to minimize the intermolecular forces of interactions (polar and/or hydrogen-bonding interactions) between the foulants and the membrane surface. The hydrophilic domains are used to bind water molecules and generate hydration layer similar with widely popular hydrophilic modification methods. Considering that foulants tend to adsorb on traditional hydrophobic membrane surfaces driving by the decrease of the Gibbs free energy of the system, the surface energy of membranes is regarded as one of the most relevant physicochemical parameters influencing free energy of the adsorption process. The reduction of the surface...
