“…In short, NIGs have been rather attractive for various research areas and potential technological applications in actuators, 33,34 ionic thermoelectric capacitors, 35 solid-state batteries, 36 transistors, 37 wearable sensors, [38][39][40][41][42][43] flexible supercapacitors, [44][45][46][47][48][49][50] and so forth. [51][52][53][54] This is attributed to the unique combination of several significant improved properties that NIGs offer, compared with plain IGs and conventional materials. As aforementioned, ascribing to high SSAs, nanostructured matrices in the NIGs could promote greater interactions with ILs, resulting in much-improved properties such as high ionic conductivity, outstanding thermal stability, enhanced mechanical strength, and robust electrochemical performances, as shown in Figure 2.…”

To utilize intermittent renewable energy to achieve carbon neutrality, rechargeable lithium‐based batteries have been deemed to be the most promising electrochemical systems for energy supply and storage. However, there still exist safety issues and challenges, especially originating from the intrinsic volatility and flammability of the electrolytes used in lithium‐based batteries. Due to the unique advantages of better safety, (quasi) solid‐state electrolytes have been exploited. Ionogel (IG), known as ionic liquid (IL) based monolithic quasi‐solid‐state electrolyte separator, consists of IL and gelling matrix and has become an active area of research in lithium‐based battery technology, owing to fascinating exotic characteristics including high safety (thermal stability) under extreme operating conditions, wide processing compatibility, and decent electrochemical performances. Among various gelling matrices, nanomaterials are very promising to simultaneously enhance ionic conductivity, mechanical strength, and thermal and electrochemical properties of IGs, which make the nanocomposite ionogels (NIGs). Herein, several significant advantages of NIGs as monolithic electrolyte membranes are briefly described. Also, recent advances in the NIGs for Li‐ion batteries, Li‐metal batteries, Li‐S batteries, and Li‐O2 batteries are timely and systematically overviewed. Finally, the remaining challenges and perspectives on such an interesting and active field are discussed. To the best of our knowledge, there are rare review articles focusing on the NIGs for Li‐based batteries till now. This work could offer a comprehensive understanding of recent advances and challenges of NIGs for advanced lithium storage.

Conductive hydrogels with self-adhesive property have received increasing attention in the fields of human−computer interaction, smart wearable devices, and soft electronic materials; however, they are easily contaminated by oil due to their sticky property, which will degrade their appearance and performance in daily use and make it difficult to be used in the complex oily water environment. Herein, a type of Janus TA@PVA/PSBMA hydrogel with slippery oil repellency and sticky adhesion is prepared by partially compounding the PVA/PSBMA hydrogel with tannic acid (TA) molecules through a unilateral soaking method. The upper PVA/PSBMA hydrogel layer in the Janus hydrogel exhibits excellent antioil fouling capability in air, underwater, and even under oil environments, because of the strong water affinity of the zwitterionic PSBMA chains. Interestingly, the bottom TA@PVA/PSBMA hydrogel layer can adhere to various substrates with bonding strength through active interactions between the TA molecules and the substrates. Exploiting its conductive, antifouling, and selfadhesive properties, the obtained Janus TA@PVA/PSBMA hydrogel is demonstrated as a strain sensor that can stably monitor large and subtle body movements in air, underwater, and oily wastewater. This work is expected to present a material for reliable sensing in complex environments.

“…Based on the percolation theory, only a small amount of conductive filler can result in a high ε in polymers due to the obviously improved interfacial polarization (IP) effect near the percolation transition (f c ). 13,14 The advantage of this method is unavoidably also accompanied by a sharply increasing loss and leakage conductivity near the f c . So far, it is still difficult to simultaneously achieve extremely low loss and high ε when obtaining composites with good integrated dielectric properties.…”

Morphological engineering of SiO₂ interlayer towards meliorative dielectric and thermal properties in β‐SiC_w@SiO₂/PVDF composites

Polymers with high thermal conductivity (TC) and dielectric constant (ε) but low dielectric loss show enormously potential applications in electrical power systems. To enhance the ε and TC while significantly suppressing the loss of β‐silicon carbide whisker (β‐SiCw)/polyvinylidene fluoride (PVDF), in this study, SiO2 shells with different morphologies were constructed on the superficies of β‐SiCw via a facile oxidation method in air atmosphere. The SiO2 shell’ morphology on the TC and dielectric performances of the β‐SiCw@SiO2/PVDF are systematically explored as a function of the frequency and filler loading. The β‐SiCw@SiO2/PVDF demonstrate astonishingly restricted loss and meliorative TC when compared to the β‐SiCw/PVDF because the SiO2 shell not only suppresses the β‐SiCw from direct contact with one another and impedes the long‐distance charges migration thereby resulting in rather low loss and leakage conductivity, but also restrains the thermal interfacial resistance via increased interfacial compatibility and interactions. The concurrent enhancement effect in the ε and TC but low loss of the composites is more evident in the crystalline SiO2 interlayer with a high TC compared with amorphous one. These results provide insight into the exploration of composite nanodielectrics with large TC and ε but low loss for applications in electrical power systems.Highlights Core@shell structured β‐SiCw@SiO2/PVDF were obtained by a facile oxidation. The great reduction in both loss and conductivity is attributed to the SiO2 shell. Crystalline SiO2 shell can improve the composites' thermal conductivity. The SiO2 shell prevents long‐range carrier migration.
