“…According to the ATR-FTIR spectra (Figure S2), the band arising from the asymmetric stretching vibration of SO (υ SO ) shifted from 1189 to 1196 cm −1 after adding AM. 29 The fact suggested that the HSO 4 − anion as acceptor formed a hydrogen bond with the N−H group of AM, 30 regulating the amphiphilic distribution of ImHS to induce the micellar aggregation. The isotropic micellar solution allowed AM to disperse uniformly in the precursor.…”

Lyotropic self-assembly of ionic surfactants benefits the construction of ion-conductive pathways but suffers from poor mechanical stability owing to the intrinsic fluidity. Here, a novel mesomorphic polymer hydrogel, featuring a porous network of the cross-linked polymer trapping lyotropic selfassembly of ionic surfactants, is presented for fuel cells. The mesomorphic hydrogel, which is facilely derived from radical polymerization of an acrylamide monomer and a cross-linker in an aqueous solution of 1-tetradecyl-3methylimidazolium hydrogen sulfate, exhibits not only a lamellar lyotropic liquid crystal phase but also reversible tensile, compressive, and shear deformations. Macroscopic alignment of the mesomorphic hydrogel is achieved by lowfrequency shear, and ionic conductivity is promoted to 166 mS cm −1 by virtue of the aligned ion-conductive channels. A hydrogen fuel cell is fabricated from the mesomorphic polymer hydrogel, and a peak power density of 48 mW cm −2 is achieved. Overall, this work provides a strategy to endow functional lyotropic self-assembly with mechanical strengths for diverse electrochemical applications.

“…Many of these applications are surrounding the use of ILs in electrochemical devices and energy storage. Novel polymerised ILs (polyILs) combine the high ionic conductivity and electrochemical stability benefits of the IL, with the mechanical stability and flexibility of polymers [244]. PolyILs can find uses in solid-state batteries, offering a leak-free, non-volatile, and non-flammable alternative to classical liquid-based electrolytes [245].…”

Industrial Applications of Ionic Liquids

Since their conception, ionic liquids (ILs) have been investigated for an extensive range of applications including in solvent chemistry, catalysis, and electrochemistry. This is due to their designation as designer solvents, whereby the physiochemical properties of an IL can be tuned for specific applications. This has led to significant research activity both by academia and industry from the 1990s, accelerating research in many fields and leading to the filing of numerous patents. However, while ILs have received great interest in the patent literature, only a limited number of processes are known to have been commercialised. This review aims to provide a perspective on the successful commercialisation of IL-based processes, to date, and the advantages and disadvantages associated with the use of ILs in industry.

“…) what one observes in case of SDWHBs is dynamic disorder of protons due to barrier hopping and not proton delocalization as in case of LBHB. Proton conductions studies [25] have demonstrated that in order to have large proton conductivity presence of SDWHB is required within the material; in contrast presence of LBHB can result in lower conductivity due to partial proton transfer.…”

Hydrogen bonding is a complex phenomenon that is a resultant of many energy components like the electrostatic, dispersive, covalent, charge cloud overlap repulsion etc, nature of hydrogen bond (H-bond) depends on which of these components play a dominant role. Low barrier hydrogen bond (LBHB) constitutes a special category of hydrogen bonds characterized by near delocalization of proton between donor and acceptor groups of the H- bond unlike an ordinary hydrogen bond (OHB) having proton clearly localized near the donor group. The significance of LBHBs in macromolecular interactions has been highly controversial, despite may attempts the existence and potential importance of protein LBHBs remains debatable. In order to answer questions like whether or not a distinct class of LBHBs exists and if they do exist under what conditions they are formed and how do they behave differently from OHBs, a detailed study of H-bonding in Diglycine Perchlorate (DGPCl) crystal containing five unique hydrogen bonded glycinium-glycine pairs is undertaken. All O-H---O bonds of DGPCl are between the carboxyl (-COOH) and carboxylate (-COO-) groups with slightly different electron distributions resulting in observable variations in the H-bond geometries, this is an indication of varying strength of these short strong H-bonds. It is found that LBHB nature of the five O-H—O bonds between glycinium-glycine pairs (P1-P5) varies as P1<P4<P2<P3<P5. This study gives an experimental evidence of the existence of LBHBs and demonstrates that the behaviour of LBHBs is very different from that of strong OHBs.
