We demonstrate that surface modified nanocellulose fibers (NCFs) can be used as substrates to synthesize supercapacitor electrodes with the highest full electrode-normalized gravimetric (127 F g(-1)) and volumetric (122 cm(-3)) capacitances at high current densities (300 mA cm(-2) ≈ 33 A until date reported for conducting polymer-based active mass loadings 9 mg cm(-2). By introducing quaternary amine groups on of NCFs prior polypyrrole (PPy) polymerization, macropore volume formed PPy-NCF...
One of the biggest challenges we will face over next few decades is finding a way to power future while maintaining strong socioeconomic growth and clean environment. A transition from use fossil fuels renewable energy sources expected. Cellulose, most abundant natural biopolymer on earth, unique, sustainable, functional material with exciting properties: it low‐cost has hierarchical fibrous structures, high surface area, thermal stability, hydrophilicity, biocompatibility, mechanical...
It is a challenge to design Ti3C2Tx MXene-based electromagnetic interference (EMI) shielding composites with excellent mechanical properties. Herein, highly robust, flexible and durable MXene/carbon fiber fabric/thermoplastic polyurethanes (Ti3C2Tx MXene/CFf/TPU) composite was fabricated through simple electrohydrodynamic atomization deposition, layer-by-layer stacking hot pressing technology. The synergistic strengthening effect of van der Waals forces covalent bonds can improve the tensile...

Potassium vanadium fluorophosphate (KVPO 4 F) is regarded as a promising cathode candidate for potassium-ion batteries due to its high working voltage and satisfactory theoretical capacity. However, the usage of electrochemically inactive binders redundant current collectors typically results in inferior electrochemical performance low energy density, thus implying important role rational electrode structure design. Herein, we have reported scalable cost-effective synthesis cellulose-derived...
