Abstract Over the past two decades, deep eutectic solvents (DESs) have captured significant attention as an emergent class of that unique properties and applications in differing fields chemistry. One area where DES systems find utility is design polymeric gels, often referred to “eutectogels,” which can be prepared either using a replace traditional solvent, or monomers form part themselves. Due extensive network intramolecular interactions (e.g., hydrogen bonding) ionic species exist systems, eutectogels possess appealing material properties—high adhesive strength, tuneable viscosity, rapid polymerization kinetics, good conductivity, well high strength flexibility. In addition, non‐covalent crosslinking approaches are possible due inherent these materials. This review considers several key eutectogels, including organic electronics, wearable sensor technologies, 3D printing resins, adhesives, range various biomedical applications. The design, synthesis, discussed, addition advantages this synthetic approach comparison gel design. Perspectives on future directions field also highlighted.

Abstract Herein, the photopolymerization of metal‐salt/amide‐based deep eutectic monomers (DEMs) derived from lithium, sodium, and potassium bis(trifluoromethanesulfonyl) imide (LiTFSI, NaTFSI, KTFSI, respectively) is described. Three series DEMs consisting N ‐isopropyl acrylamide (NIPAM) three different metal salts KTFSI) are tested at various molar ratios to identify suitable combinations. NIPAM/LiTFSI (1/0.2, 1/0.3, 1/0.4, 1/0.5) NIPAM/NaTFSI (1/0.2 1/0.3) obtained as liquid by simple mixing under ambient conditions (≈25 °C in air), while NIPAM/KTFSI (1/0.1, 1/0.2, a DEM 50 °C. The nature species NIPAM/metal salt ratio affected characteristic features specific interactions. Ultrafast achieved using LED‐UV light, with nearly complete monomer conversion attained within 10 s. mechanical thermal properties polymerized (PDEMs) depended substantially on ratio. P(NIPAM/0.2LiTFSI) 20 wt.% succinonitrile (SN) serving plastic crystal exhibited highest ionic conductivity (1.05 × −4 S cm −1 55 °C), P(NIPAM/0.2NaTFSI) P(NIPAM/0.2KTFSI) also improved conductivities 4.19 −5 6.64 , respectively, SN.
