NANOCOMPOSITES OF ZINC OXIDE ON GRAPHENE OXIDE: A RAPID REDUCTION OF GRAPHENE OXIDE

Digest Journal of Nanomaterials and Biostructures, 2021
In this work, graphene oxide (GO) and ZnO were synthesized using the modified Hummers method and the Spanhel and Anderson method, respectively. ZnO/GO composites were then successfully synthesized using a fast and direct process. The results of the X-ray diffraction, scanning electron microscopy (SEM), Raman spectroscopy, and Fourier-transform infrared

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Mechanical Behavior and Fracture Mechanisms of MXene/PVDF Nanocomponsites: In Situ Characterization and Multiscale Analysis

Advanced Functional Materials, EarlyView.
Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...
