Summary: Developing a new strategy to prevent the restacking of MXene nanosheets is crucial for designing flexible supercapacitor electrodes. In this study, a novel Ti3C2Tx/PVA porous sponge was prepared and used as a template for in-situ PANI polymerization. The resulting PANI@Ti3C2Tx/PVA hydrogel composite exhibited both double-layer capacitance and pseudocapacitance behavior, and demonstrated excellent capacitance, energy density, and power density. The capacitance of this supercapacitor remained almost unchanged under different bending angles, and showed 99% capacitance retention after 10,000 charge/discharge cycles.

Summary: Flexible sensing is a core technology for the new generation of the industrial internet, enabling flexibility in information acquisition, processing, transmission, and display by changing the physical form of traditional electronic devices. Conductive fabrics, essential for flexible sensing, often suffer from weak adhesion of conductive fillers and rapid deterioration of conductive properties after repeated stretching. This study proposes using multifunctional nanosilver as a conductive filler, enhancing adhesion by growing nanosilver in situ on fabric fibers. The resulting conductive fabric exhibits improved conductivity and stability, with minimal increase in square resistance even after 60 stretches.

Summary: The study synthesized graphene-zinc oxide nanocomposite for use in electrospun PVDF nanofibers, resulting in uniform, bead-free nanofibers with improved piezoelectric properties. The addition of synthesized G-ZnO nanocomposite decreased nanofiber diameter and increased the crystalline and polar beta phase of PVDF nanofibers, leading to superior peak-to-peak voltage compared to pristine PVDF and PVDF/ZnO nanofibers. These findings offer new insights for the development of flexible piezoelectric nanofibrous devices and energy harvesting systems.

Summary: Anti-felting process for woolen goods is typically carried out using water-based chlorination, which releases chlorine-containing discharge into the environment. In this study, deep eutectic solvents (DESs) were introduced as green substitutes for sodium hypochlorite to achieve anti-felting properties on woolen goods. The DES called Reline, a mixture of choline chloride and urea, showed promising results as a green anti-felting agent and non-aqueous reaction medium. Reline-treated wool exhibited reduced shrinkage, preserved physical and mechanical properties, improved whiteness, and lower yellowness compared to hypochlorite-treated fibers.
