“…5(A)). 78 Using even a small amount of IA in the PDES formulation (AA : IA : ChCl = 2 : 0.3 : 1 mole ratio) produced polyDES with superb mechanical properties (maximum strain and stress at break of around 1456% and 5.3 MPa, respectively), revealing the superior ability of this dicarboxylic acid for hydrogen bonding compared to MA and AMPS. However, higher non-covalent cross-linking in these elastomers could stunt the free movement of ions, negatively affecting their ionic conductivity, which was 2.76 × 10 −4 S m −1 , significantly lower than those for poly(AAm/ChCl- co -MA/ChCl) and poly(AA/ChCl- co -MA/ChCl).…”

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

Polymerizable deep eutectic solvents (PDES) represent a novel class of ionic liquids characterized by the presence of polymerizable groups in their hydrogen‐bond donor or acceptor components. Within the realm of flexible electronics, PDES is emerged as a promising material for the fabrication of sensors that exhibit both flexibility and stretchability. This research employs the UV‐initiated photocopolymerization of a ternary PDES composed of choline chloride (ChCl), 2‐hydroxyethyl acrylate (HEA), and itaconic acid (IA), to synthesize an ionic conductive elastomer (ICE) that boasts desirable comprehensive performances, which can be controlled by meticulously adjusting the ratios of these components. The fabrication process is streamlined and efficient, utilizing cost‐effective and eco‐friendly materials. This elastomer exhibits favorable ionic conductivity (1.70 × 10−2–5.45 × 10−2 S m−1), mechanical strength (0.48–1.21 MPa stress at break, 395–701% elongation at break), adhesion capacity (49–120 kPa adhesion strength), and sensing sensitivity toward human motions.
