Ion selective membranes
Abstract
Efficient ion sieving through artificial ion-selective membranes (ISMs) is the key parameter to extend separation technologies and improve analytical chemistry approaches. In an effort to provide a general overview of current progress in designing, manufacturing, and implantation of ISMs, this review paper gives a broad picture of the different types and various applications of ISMs. Generally, the process of selective ions transfer across the membranes relies on two dominant mechanisms of size exclusion and charge repulsion. Inspired by the natural membranes, the key players responsible for controlling ion transfer through ISMs are acceptor/ionophore components and nanopores/nanochannels. Since the early development of conventional plasticized-dependent ISMs in the mid-1960s, a wide spectrum of constituent materials, fabrication methods, and regulatory parameters have been applied to improve the selectivity and sensitivity of membranes. Taking into account these concepts, ISMs have been employed in various applications ranging from environmental and biomedical applications to manufacturing redox flow batteries and electrochemical energy storage systems. © 2023 Elsevier Inc.
