Polymers of Intrinsic Microporosity (PIMs) are broadly recognized as a potential next generation membrane material for gas separations due to their ultra-permeable characteristics. This mini review aims to provide an overview of these materials and capture its very essence, from chemistry to applications. PIMs-based gas separation membranes are divided into three main categories, i.e., neat PIMs, polymer blend PIMs, and mixed matrix PIMs membranes. This review covers a wide spectrum of PIMs with their gas diffusion mechanisms and separation performance, all of which are examined in detail. Core challenges and opportunities of PIMs membrane technology are reviewed, and this article concludes with future perspectives on PIMs. This mini review establishes a comprehensive understanding of the key technological competence and barriers of PIMs for next-generation gas separations membranes.
