Hydrogel electrolytes have gained significant attention in the field of flexible supercapacitors for their intrinsic safety, high flexibility, and superior ionic conductivity. However, water-rich structures traditional hydrogel inevitably cause them to freeze at subfreezing temperatures, which therefore limits application extremely cold temperatures. Herein, an organohydrogel electrolyte was successfully fabricated by displacing a portion water molecules from hydroxypropyl...
A novel PAEK/PAEK-<italic>g</italic>-PEG blend MPE with a chitosan-based LiClO<sub>4</sub> gel electrolyte was prepared and applied in an S-EDLC.
A novel semicrystalline poly(ether ketone) (PEK)-based proton exchange membrane (semi-SPEK-x) has been developed. Through a one-step sulfonation and hydrolysis, ketimine) precursor transforms into PEK ion-conducting groups are introduced. With an ion-exchange capacity ranging from 1.49 to 2.00 mequiv g-1, the semi-SPEK-x polymers exhibit feature in both dry hydrated states. Owing domains inside polymer, obtained exhibits low water uptake volume swelling ratio. More importantly, structure...
Abstract In order to improve the poor solvent resistance and temperature caused by traditional sizing agents, crystalline poly(ether ether ketone) (PEEK) is introduced interfacial phases of carbon fiber (CF) reinforced PEEK composites a soluble precursor named PEEK‐1,3‐dioxolane. By changing molecular weight concentration in solution, content coated on CF surface can be controlled different properties obtained. The results shows that, with this method, completely surface, shear strength...
Abstract New bisphenol monomers, (3‐methyl)phenylhydroquinone and (3‐trifluoromethyl)phenylhydroquinone, were prepared in a two‐step synthesis. A series of poly(aryl ether ketone)s derived from these bisphenols via nucleophilic aromatic substitution polycondensation with various bisfluoro compounds. The proceeded quantitatively tetramethylene sulfone the presence anhydrous potassium carbonate afforded polymers inherent viscosities 0.63–0.91 dL/g. fluorinated showed lower glass‐transition...
Abstract A fast and highly efficient approach for the synthesis of hyperbranched poly(aryl ether ketone)s (HPAEKs) via polycondensation 2 BB′ monomers is described. Commercially available hydroquinone (HQ, monomer) easily synthesized 2,4′,6‐trifluorobenzophenone (TF, were thermally polycondensed to prepared fluoro‐ or phenolic‐terminated HPAEKs with K CO 3 Na as catalysts. During reaction, fluorine at 4′‐position TF reacts rapidly phenolic group HQ, forming predominantly dimers some other...
We report a nanobelt structured MoO3 intimately wired by carbon nanotube (CNT) networks using facile hydrothermal synthesis approach. The CNT not only serve as highly conducting and porous scaffold facilitating electron ion transport but also provided extra space for buffering of strain stress upon electrochemical Li insertion extraction. resulting nanobelt/CNT (MoO3/CNT) hybrid structures show improved performance compared with the pristine material, regardless presence nearly non-active...
