The development of membrane technologies began in the early 20th century. Since then, aspects such as the methodology of forming membranes, the materials from which they are obtained, the way they are applied, and the possibilities for their application have changed significantly. One of the types of membranes most often utilized by scientists, among others, due to their simplicity, is polymer inclusion membranes (PIMs). The modifications currently being introduced in PIMs primarily concern their composition (type of polymer, carrier/extractant, plasticizer, or presence of additional functional substances). These changes are made to help obtain the membranes that are cheaper to produce, environmentally friendly, and selective for the type of transported substance. In the presented review article, the latest achievements in the field of modification of PIMs were noticed. Described herein are selected articles published in recent years in journals important for this field of science.
