Abstract One-dimensional flexible supercapacitor yarns are of considerable interest for future wearable electronics. The bottleneck in this field is how to develop devices high energy and power density, by using economically viable materials scalable fabrication technologies. Here we report a hierarchical graphene–metallic textile composite electrode concept address challenge. electrodes consist low-cost graphene sheets immobilized on the surface Ni-coated cotton yarns, which fabricated...
Abstract Hydrogel electrolytes have high room‐temperature conductivity and can be widely used in energy storage device. However, hydrogels suffer from the inevitable freezing of water at subzero temperatures, resulting diminishment their mechanical properties. How to achieve without sacrificing hydrogels’ flexibility temperature is an important challenge. To address this challenge, a new type zwitterionic polymer hydrogel (polySH) fabricated. The anionic cationic counterions on chains...
Hydrogel electrolyte is widely used in solid energy storage devices because of its high ionic conductivity, environmental friendliness, and non-leakage property. However, hydrogel not resistant to freezing. Here, a proton conductive zwitterionic with super conductivity 1.51 mS cm-1 at -50 °C fabricated by random copolymerization acrylamide monomer the presence 1 m H2 SO4 ethylene glycol (EG). The antifreezing performance low temperature are ascribed hydrogen bonds between components water...
Designing scalable coatings with a wide spectrum of functions such as liquid repellency, anticorrosion, and antiflaming high level mechano-chemical-thermal robustness is crucial in real-life applications. However, these individual functionalities are coupled together or even have conflicting requirements on the interfacial bulky properties materials, thus, simultaneously integrating all features into one coating has proved challenging. Herein, an integral skin-inspired triple-layered (STC)...
Designing hydrogels with high mechanical properties without sacrificing their self-healing efficiencies remains great challenges. We have fabricated cationic polyacrylamide/graphene oxide (GO) by free-radical polymerization of acrylamide (AM) and 2-(dimethylamino)ethylacrylatemethochloride (DAC) in the presence GO. The ability can be tuned GO content mass ratio AM DAC. ionic bonds between DAC hydrogen efficiently dissipate energy rebuild networks. resulting composite possess stiffness...
The development of stimuli-responsive materials with the ability controllable oil/water separation is crucial for practical applications. Here, a novel pH responsive nonfluorine-containing copolymer was designed. together silica can be dip-coated on different including cotton fabric, filter paper, and polyurethane foam. coated exhibit switchable superhydrophilicity superhydrophobicity applied in continuous oil/water/oil three phase mixtures, surfactant stabilized emulsion (oil-in-water,...

Abstract Hydrogel electrolyte is not resistant to freezing and has weak mechanical properties, its fabrication time‐consuming energy‐consuming, limiting application. Here, a simple, universal, fast gelation based on dealkaline lignin (DL) ‐alkali metal ions developed. The complex formed by catechol alkali promotes the equilibrium of redox reactions. produced SO 4 − ·, OH· singlet oxygen ( 1 O 2 ) radicals are responsible for rapid polymerization vinyl monomers. Alkali play dual role in frost...
Hydrogel electrolytes with antifreezing performance and excellent mechanical properties have become a research hotspot, but the general preparation process requires time energy consumption, limiting scope of applications.
