Advances in Polymerized Ionic Liquids and Their Composites

Dear Colleagues,

Polymerized ionic liquids (PILs) and their composites, as an innovative class of polyelectrolytes, are important and versatile materials that can be tailored to overcome the current challenges in the fields of polymer and material science. These materials combine the attractive mechanical characteristics of polymers with the unique physicochemical properties of low molecular weight ionic liquids (ILs). These properties make PILs and their composites (PILs with metal salts/ metal nanostructures, carbons, silicas, organic compounds, ILs, metal–organic frameworks) appealing candidates for various applications, such as electrochemical energy storage technologies (Li, metal–air, and organic redox flow batteries, fuel cells, supercapacitors, dye-sensitized solar cells), stimuli-responsive materials, carbon materials, and antimicrobial materials, in catalysis, in sensors, in absorption, and in CO₂ separation materials. This Special Issue, “Advances in Polymerized Ionic Liquids and Their Composites”, aims to discuss all aspects regarding experimental and theoretical work on the synthesis, design, characterization, and applications of PILs and their composites. We welcome original full articles, short communications, or review articles on fundamental and applied science of PILs and their composites that tackle problems and challenges in energy, the environment, and life science, in order to contribute to the establishment of detailed correlation between material structure–property–performance relationships, processing, and utilization towards application development.
