Summary: In this study, bis-imidazole-containing ionic liquids (VDILs) with different numbers of substituted alkenyl groups were designed and synthesized, and then polymerized in aqueous solution to form hydrophobic PVDILs. The results showed that the position of the alkenyl groups in the VDIL monomers significantly influenced the molecular weight of the PVDILs. XPS and FT-IR results revealed the presence of residual alkenyl groups in the PVDIL structures. This study presents a new method for the polymerization of alkenyl-based DILs and lays a foundation for the application of PDILs.

Summary: In this study, a straightforward and scalable synthetic route was developed to fabricate poly(ionic liquid) (PIL) homopolymer nanovesicles (NVs) with tunable particle size and shell thickness. By increasing the monomer concentration, the morphology of the NVs changed from hollow structures to dense spheres and then to directional worms. The internal morphology transformation of NVs was investigated using simulations, which revealed a correlation between PIL chain length and NVs shell thickness. The functionalized PIL NVs were employed as electrocatalysts for CO2 electroreduction and exhibited enhanced selectivity towards C1 products due to strong electronic interactions with ultra-small copper nanoparticles (CuNPs).

These polymers were made of (meth)acrylic ammonium salts and biobased polyphenols bearing catechol or pyrogallol motifs. The phenolic chemistry allowed the modulation of ionic polymer properties, resulting in adhesive or tough materials. Furthermore, the phenolic polymeric deep eutectic solvents (polyDES) exhibited metal complexation ability, antibacterial properties, and fast processability by digital light 3D printing.

Summary: This study investigated the blends of polyethylene oxide (PEO) and poly(sodium 1-[3-(methacryloyloxy)propylsulfonyl]-1-(tri-fluoromethanesulfonyl) imide) (PNaMTFSI) for their application as solid electrolytes in sodium batteries. PNaMTFSI was found to decrease the crystal growth rate of PEO but increase its nucleation rate, leading to higher overall crystallization rate in the blends. The ionic conductivity of the blends was also influenced by the composition, with the highest values observed at 15 and 30 wt% PNaMTFSI.

Summary: Ca- and Mg-based batteries are more sustainable alternatives to Li-ion batteries, but suffer from poor mass transport of cations. Organic positive electrodes, although most sustainable and potentially low-cost, currently have the best electrochemical performances in Ca and Mg cells but suffer from low capacity retention upon cycling, the origin of which is not yet fully understood.
