Flexible All‐Hydrogel Supercapacitors
In article number 2309900, Jingya Nan, Yupeng Liu, Chunpeng Wang, and co‐workers develop a flexible all‐hydrogel supercapacitor that can integrate stable interface and anti‐freezing property together, which is produced by in situ polymerization of hydrogel electrolyte onto hydrogel electrodes. The constructed device demonstrates satisfactory low‐temperature capacitive...
All‐hydrogel supercapacitors are emerging as promising power sources for next‐generation wearable electronics due to their intrinsic mechanical flexibility, eco‐friendliness, and enhanced safety. However, the insufficient interfacial adhesion between the electrode and electrolyte and the frozen hydrogel matrices at subzero temperatures largely limit the practical applications of all‐hydrogel supercapacitors...
Artificial electronic skin (E‐skin), a class of promising materials mimicking the physical‐chemical and sensory performance of the human skin, has gained extensive interest in the field of human health‐monitoring and robotic skins. However, developing E‐skin simultaneously achieving high resilience, hysteresis‐free, and absent external power is always a formidable challenge. Herein, a liquid‐free...
Malleable thermosets as dynamic covalent cross‐linked polymers, simultaneously possessing the advantages of thermosets and thermoplastics, have attracted considerable attention. Although several reprocessing concepts have been demonstrated, the fabrication of fast‐curing bio‐based strong and tough malleable thermosets for advanced applications in electronics remains a great challenge. Herein, a novel...
