“…While the imidazolium ring with its planar structure has a lesser degree of conformational freedom, the TFSA anion is flexible and can undergo conformational change. As a result, the polyanion networks had lower T g s compared to the polycation networks [20,22].…”

In this work, poly(ionic liquid) (polyIL) polymer electrolytes were prepared by the free radical copolymerization of IL monomers with a plasticizing monomer having poly(ethylene glycol) (PEG) side chain. The IL monomers, i.e., the polycation and polyanion precursors, were 1-[(3-methacryloyloxy)propyl]-3-methylimidazolium bis(trifluoromethanesulfonyl)amide ([C 3 mim-MA][TFSA]) and 1-methyl-3-propylimidazolium N-[3-(methacryloyloxy)propylsulfonyl]-N-(trifluoromethanesulfonyl)amide ([C 3 mim][TFSA-MA]), respectively. The ionic conductivities of the polyIL polymer electrolytes increased with a decrease in the weight fraction of the ionic monomer owing to the plasticizing effect of the PEG side chain, whereas the mechanical strength simultaneously decreased due to a lowering in the glass transition temperature of the electrolytes. The ionic conductivities of the electrolytes were 10 −6-10 −7 S cm −1 at room temperature. Ionic polymer actuators were fabricated using the polyILs as an electrolyte layer by sandwiching the electrolyte membrane with two carbon electrodes. The displacement behavior depended entirely on the fixed charge on the polymer chain.

Branched polyelectrolytes with cylindrical brush, dendritic, hyperbranched, grafted, and star architectures bearing ionizable functional groups possess complex and unique assembly behavior in solution at surfaces and interfaces as compared to their linear counterparts. This review summarizes the recent developments in the introduction of various architectures and understanding of the assembly behavior of branched polyelectrolytes with a focus on functional polyelectrolytes and poly(ionic liquid)s with responsive properties. The branched polyelectrolytes and poly(ionic liquid)s interact electrostatically with small molecules, linear polyelectrolytes, or other branched polyelectrolytes to form assemblies of hybrid nanoparticles, multilayer thin films, responsive microcapsules, and ion-conductive membranes. The branched structures lead to unconventional assemblies and complex hierarchical structures with responsive properties as summarized in this review. Finally, we discuss prospectives for emerging applications of branched polyelectrolytes and poly(ionic liquid)s for energy harvesting and storage, controlled delivery, chemical microreactors, adaptive surfaces, and ion-exchange membranes.

“…The highest anhydrous ionic conductivity was 9.8 × 10 −6 S cm −1 for GTP‐EG3‐MePyrro·Tf 2 N (at 30 °C). Shaplov et al reported the ionic conductivity of 7.6 × 10 −7 S cm −1 for the methacrylate polymer with the MePyrro unit (at 25 °C) . Compared to Shaplov's poly(ionic liquid)s, the ionic conductivity of our polymer is better owing to the molecular design using the flexible polyether.…”

“…In our previous study, we characterized the imidazolium‐based poly(ionic liquid)s . Although there are many studies on the imidazolium‐based poly(ionic liquid)s, the report on the other quaternary ammonium cation‐based poly(ionic liquid)s is rare . In this study, we prepared eight types of cationic GTPs from combinations of four cationic units [pyrrolidinium, piperidinium, morpholinium, and N , N ‐diethyl‐substituted ammonium; Pyrro, Pipe, Morph, and NEt 2 , respectively] and two N ‐alkyl substituents [methyl and ethyl groups; Me and Et, respectively] (Figure ).…”

Eight types of cationic glycidyl triazole polymers (GTPs) are prepared from combinations of four quaternary ammonium cationic units (pyrrolidinium, piperidinium, morpholinium, and N,N‐diethyl‐substituted ammonium) and two N‐alkyl substituents (methyl and ethyl groups). These poly(ionic liquid)s are prepared using Cu(I)‐catalyzed azide‐alkyne cycloaddition reaction between the alkyne derivatives of ionic liquids and glycidyl azide polymer. The ionic conductivity is characterized by impedance measurement. The ionic conductivity depends on the type of the cationic unit, but the type of the N‐alkyl substituent shows little influence on the ionic conductivity. The order of the cationic units that afford high ionic conductivity is as follows: pyrrolidinium >N,N‐diethyl‐substituted ammonium > piperidinium > morpholinium. The highest anhydrous ionic conductivity obtained in this study is 9.8 × 10−6 S cm−1 at 30 °C for the GTPs with the 1‐methylpyrrolidinium unit. Based on electrode polarization analysis, the conducting ion (carrier) concentration and mobility are calculated.
