“…16 In particular, for a polar molecular ERF, 17 although it has higher mechanical properties, the existence of polar molecules on the surface of the dispersed phase leads to an ERF with poor thermal stability and large leakage current density. 18 To solve this problem, some researchers have used intrinsically polarizable materials, 19 such as conductive polymers, [20][21][22][23] carbon nanotubes, 24,25 graphene oxide (GO), 26 and poly(ionic liquids), [27][28][29][30] to develop a variety of ERFs. But the low yield stress or large zerofield viscosity of these ERFs limits their practical applications.…”

The breadth and importance of polymerized ionic liquids (PILs) are steadily expanding, and this review updates advances and trends in syntheses, properties, and applications over the past five to six years. We begin with an historical overview of the genesis and growth of the PIL field as a subset of materials science. The genesis of ionic liquids (ILs) over nano to meso lengthscales exhibiting 0D, 1D, 2D, and 3D topologies defines colloidal ionic liquids, CILs, which compose a subclass of PILs and provide a synthetic bridge between IL monomers (ILMs) and micro to macroscale PIL materials. The second focus of this review addresses design and syntheses of ILMs and their polymerization reactions to yield PILs and PIL-based materials. A burgeoning diversity of ILMs reflects increasing use of nonimidazolium nuclei and an expanding use of step-growth chemistries in synthesizing PIL materials. Radical chain polymerization remains a primary method of making PILs and reflects an increasing use of controlled polymerization methods.Step-growth chemistries used in creating some CILs utilize extensive cross-linking. This cross-linking is enabled by incorporating reactive functionalities in CILs and PILs, and some of these CILs and PILs may be viewed as exotic cross-linking agents. The third part of this update focuses upon some advances in key properties, including molecular weight, thermal properties, rheology, ion transport, self-healing, and stimuli-responsiveness. Glass transitions, critical solution temperatures, and liquidity are key thermal properties that tie to PIL rheology and viscoelasticity. These properties in turn modulate mechanical properties and ion transport, which are foundational in increasing applications of PILs. Cross-linking in gelation and ionogels and reversible step-growth chemistries are essential for self-healing PILs. Stimuli-responsiveness distinguishes PILs from many other classes of polymers, and it emphasizes the importance of segmentally controlling and tuning solvation in CILs and PILs. The fourth part of this review addresses development of applications, and the diverse scope of such applications supports the increasing importance of PILs in materials science. Adhesion applications are supported by ionogel properties, especially crosslinking and solvation tunable interactions with adjacent phases. Antimicrobial and antifouling applications are consequences of the cationic nature of PILs. Similarly, emulsion and dispersion applications rely on tunable solvation of functional groups and on how such groups interact with continuous phases and substrates. Catalysis is another significant application, and this is an historical tie between ILs and PILs. This component also provides a connection to diverse and porous carbon phases templated by PILs that are catalysts or serve as supports for catalysts. Devices, including sensors and actuators, also rely on solvation tuning and stimuliresponsiveness that include photo and electrochemical stimuli. We conclude our view of applications with 3D printi...

Small-molecule ionic liquids (ILs) are frequently employed as efficient bulk phase modifiers for perovskite materials. However, their inherent characteristics, such as high volatility and ion migration properties, pose challenges in addressing the stability issues associated with perovskite solar cells (PSCs). In this study, we design a poly(IL) with multiple active sites, named poly[4-styrenesulfonyl(trifluoromethylsulfonyl)imide]pyridine (P[STFSI][PPyri]), as an efficient additive of perovskite materials. The S=O in the sulfonyl group chelates with uncoordinated Pb 2+ and forms hydrogen bonds with the organic cations in the perovskite, suppressing the volatilization of the organic cations. The N + in pyridine can fix halide ions through electrostatic interaction with I − and Br − ions to prevent halide ion migration. P[STFSI][PPyri] demonstrates the ability to passivate defects and suppress nonradiative recombination in PSCs. Additionally, it facilitates the fixation of organic and halide ions, thereby enhancing the device's stability and photoelectric performance. Consequently, the introduction of P[STFSI][PPyri] as a dopant in the devices resulted in an excellent efficiency of 24.62%, demonstrating outstanding long-term operational stability, with the encapsulated device maintaining 87.6% of its initial efficiency even after 1500 h of continuous maximum power point tracking. This strategy highlights the promising potential of poly(IL) as an effective additive for PSCs, providing a combination of high performance and stability.
