“…The hydrogel electrolyte had excellent pressure resistance and was resistant to high salt solution environments, and more specifically, the hydrogel had a water content of 96%. [ 196 ] The authors first complexed the 2‐acrylamide 2‐methyl‐1‐propane sulfonic acid (AMPS) monomer in an aqueous solution via SO 3 − ‐H 3 NHNCO‐ionic bonding, and subsequently, cross‐linked AMPS with PEGDA polymerization by UV irradiation using oxoglutaric acid as an initiator to synthesize. The interpenetrating polymer system (IPS) based on PAMPS and poly acryloyl hydrazine (PAHz) was synthesized.…”

“…Currently, most hydrogels are used to design capacitors as power sources or to connect circuits to detect signals, which have a single signal pattern and cannot be adapted to extreme environments. Yiming et al used copolymers of acrylate monomers with super‐stretchability (ethylene glycol methyl ether acrylate (MEA) and isobutyl acrylate (IBA)) as a single network polymer base with hydrophobic, [ 196 ] and high ionic conductivity and low viscosity polymeric ionic liquid (IL) 1‐ethyl‐3‐ methylimidazolium bis(trifluoromethanesulfonyl) imide as ionic conductive phase ( Figure a), the ionic hydrogel had strong adhesion to dielectric elastomers, so the authors designed an Ionogels–VBH–Ionogels–VBH four‐layer capacitive ionic skin (Figure 20b) that could convert mechanical stimuli and temperature into four signals of resistance, capacitance, OCV and SCC for transmission without external power supply, the ionic hydrogel had good environmental stability (‐60 °C to 200 °C) and mechanical stability, the fracture strain exceeded 2000%, and it did not absorb water in high relative humidity environment, and hardly lost liquid components during long time mechanical loading.

Hydrogels have been widely explored to adapt to different application circumstances. As typical wet‐soft materials, the high‐water content of hydrogels is beneficial to their wide biomedical applications. Moreover, hydrogels have been displaying considerable application potential in some high‐tech areas, like brain‐computer interface, intelligent actuator, flexible sensor, etc. However, traditional hydrogel is susceptive to freezing below zero, dehydration, performance swelling‐induced deformation, and suffers from mechanical damage in extremely mechanical environments, which result in the loss of wet‐soft peculiarities (e.g., flexibility, structure integrity, transparency), greatly limiting their applications. Therefore, reducing the freezing point, improving the dehydration/solution resistance, and designing mechanical adaptability are effective strategies to endow hydrogels with the extreme environmental adaptability, thus broadening their application fields. This review systematically summarizes research advances of environmentally adaptive hydrogels (EAHs), comprising anti‐freezing, dehydration‐resistant, acid/base/swelling deformation‐resistant, and mechanical environment adaptive hydrogels (MEAHs). Firstly, fabrication methods are presented, including the deep eutectic solvent/ionic liquid substituent, the addition of salts, organogel, polymer network modification, and double network (DN) complex/nanocomposite strategy, etc. Meanwhile, the features of different approaches are overviewed. The mechanisms, properties, and applications (e.g., intelligent actuator, wound dressing, flexible sensor) of EAHs are demonstrated. Finally, the issues and future perspectives for EAHs’ researches are demonstrated.

“…Higher water content facilitates the diffusion and transmission process of ions, therefore improving the ionic conductivity. [ 25,76,103 ] In 1997, Pissis and Kyritsis carried out several experiments with poly(hydroxyethyl acrylate) hydrogels and drew a conclusion that water content is an independent variable to ionic conductivity. [ 112 ] With higher water content, ions, the charge carriers, will be able to move over a longer distance rather than be confined.…”

To cater to the swift advance of flexible wearable electronics, there is growing demand for flexible energy storage system (ESS). Aqueous zinc ion energy storage systems (AZIESSs), characterizing safety and low cost, are competitive candidates for flexible energy storage. Hydrogels, as quasi‐solid substances, are the appropriate and burgeoning electrolytes that enable high‐performance flexible AZIESSs. However, challenges still remain in designing suitable and comprehensive hydrogel electrolyte, which provides flexible AZIESSs with high reversibility and versatility. Hence, the application of hydrogel electrolyte‐based AZIESSs in wearable electronics is restricted. A thorough review is required for hydrogel electrolyte design to pave the way for high‐performance flexible AZIESSs. This review delves into the engineering of desirable hydrogel electrolytes for flexible AZIESSs from the perspective of electrolyte designers. Detailed descriptions of hydrogel electrolytes in basic characteristics, Zn anode, and cathode stabilization effects as well as their functional properties are provided. Moreover, the application of hydrogel electrolyte‐based flexible AZIESSs in wearable electronics is discussed, expecting to accelerate their strides toward lives. Finally, the corresponding challenges and future development trends are also presented, with the hope of inspiring readers.

“…This PVDF/lean DES skeleton phase lays the foundation for high modulus and strength of the Neu‐PE. The articular cartilage with a much lower hardness <1 MPa [ 33 ] covers the bone tissue and directly contacts the synovial fluid, playing the role in protecting the bone tissue. Similarly, the UHMWPEO/PVDF/DES complex with greater access to DES becomes softer and locates at the interphase due to the nano‐phase separation.…”

To overcome the critical safety and performance issues of lithium metal batteries, it is urgent to develop advanced electrolytes with multi‐defensive properties against fire, mechanical puncture, and dendrite growth simultaneously, in addition to high ion‐conductivity. However, realizing these essential properties by one electrolyte has proved to be extremely challenging due to the inherent conflicts among them. Herein, to circumvent this challenge, a neuron‐like gel polymer electrolyte (simply referred as Neu‐PE) to simultaneously achieve supertoughness, nonflammability, dendrite‐suppression capability and self‐driven property is reported. This Neu‐PE takes advantage of nano‐phase separation regulated by highly ion‐conductive deep‐eutectic solvent. As a result, the Neu‐PE holds high ambient ionic conductivity (1.27±0.09 mS cm−1), super‐toughness and strength (22.52 MJ m−3 and 13.5±0.6 MPa), fire resistance and importantly, lithium‐metal anode protection capability. Lithium metal batteries assembled with this multi‐defensive Neu‐PE can work normally even under metal‐probe puncture or serious damage by cutting.
