“…[34] While there are some examples for the polymerization of cationic vinyl monomers since 1970s, [35,36] it was only around the year 2000, pioneered by Ohno et al, that vinylimidazolium and vinylpyridinium salts were pursued as monomers for the creation of solid polymer electrolytes. [37][38][39] Since then, polymeric ionic liquids have become ubiquitous in the literature with research led by Long, [40][41][42][43] Texter, [44,45] Yuan, [46][47][48] Merceyyes, [30,49,50] Shaplov, [51][52][53][54][55] Drockenmuller, [56][57][58] and others to name a few. [59,60] The improved processability of polymers combined with the chemical utility and derivatizability of ionic liquids is the cornerstone for their interest and broader use.…”

Photopolymerization is a convenient fabrication technique with the power to control the polymerization in both time and space, be solvent free, and use simple equipment to initiate the polymerization reaction. These features are conditional on use of liquid monomers and crosslinkers that do not require solvent for processing. One class of compounds that provides these opportunities are ionic liquid (IL) monomers, which possess negligible vapour pressure and are free‐flowing liquids at room temperature. For these reasons, ILs and photopolymerization are complementary to each other towards the fabrication of electrolyte materials by circumventing the innate difficulty in processing PILs as melts. Instead, the electrolyte polymer is formed as a crosslinked material directly where it will be used. In this review, we outline recent work demonstrating the key benefits of this unlikely marriage, including formulation design, applications in coatings, membranes, and others.

“…Furthermore, they are particularly attractive since they can be designed for specific applications, giving rise to the so-called task-specific ILs [5]. These remarkable properties make ILs suitable for a wide variety of applications in separation processes [6,7], catalysis [8], energy management [9], and material science [10,11,12,13,14].…”

“…processability, robustness) with the unique properties of ILs such as high CO 2 sorption capacity, tunable physicochemical properties, and high thermal stability [3][4][5]. The majority of the PILs based on imidazolium, pyrrolidinium, or ammonium have been synthesized via free radical polymerization and show high CO 2 permeability but low operation temperature and poor mechanical stability [6][7][8][9]. In order to overcome these obstacles and further increase the operation temperature, improve the separation properties and broaden their application range, the combination of a polymeric ionic liquid with a high glass transition temperature (T g ) polymer seems to be an ideal solution [10][11][12].…”

Polymeric (ionic liquid) (PIL) copolymers bearing cationic imidazolium pendants and polar acrylic acid groups (P(VBCImY-co-AAx)), which both favor the interaction with CO2 molecules, have been synthesized and blended with film forming, high glass transition temperature aromatic polyether-based pyridinium PILs (PILPyr). The blend membranes based on the above combination have been prepared and characterized in respect to their thermal and morphological behavior as well as to their gas separation properties. The used copolymers and blends showed a wide range of glass transition temperatures from 32 to 286 °C, while blends exhibited two phase morphology despite the presence of polar groups in the blend components that could participate in specific interactions. Finally, the membranes were studied in terms of their gas separation behavior. It revealed that blend composition, counter anion type and acrylic acid molar percentage affect the gas separation properties. In particular, PILPyr-TFSI/P(VBCImTFSI-co-AA20) blend with 80/20 composition shows CO2 permeability of 7.00 Barrer and quite high selectivity of 103 for the CO2/CH4 gas pair. Even higher CO2/CH4. selectivity of 154 was achieved for PILPyr-BF4/P(VBCImBF4-co-AA10) blend with composition 70/30.
