Superamphiphilic Polymeric Coating in Membrane Application: A Mini- Review

Abstract: Membrane technology as one of the most efficient and cost-effective separation methods has been mainly considered for different applications. But as with any method, there are some special drawbacks in membranes such as fouling, concentration polarization, and durability, which can limit the membrane performance in terms of permeate flux and solute rejection. Superamphiphilic polymers have different applications in different fields which include liquid-liquid separation membranes, self-healing, antifouling, self-cleaning, and adsorbent coatings. Recently, these kinds of coatings were applied on different membrane systems and the effects of coating on the membrane performance were evaluated. As a review, an overview on the most common methods for manufacturing membranes with superamphiphilic surface, a general review of the explored practical applications of such coatings in membranes, conclusions about the current situation of research, and commercial applications of superamphiphilic membranes are presented in this study.
