Dynamic Bonds Reinforced Polyamide Elastomer for Biomedical Orthosis

open access: yesAdvanced Science, EarlyView.
A dynamic bonds (DBs) reinforced shape memory polyamide elastomer is developed using reactive extrusion. Dynamic covalent networks enhance interlayer adhesion in 4D‐printed objects by utilizing the combined effects of multiple DBs, reducing mechanical anisotropy and improving the mechanical and shape memory properties.

A General Strategy for Bandgap Engineering Via Anion‐Lattice Doping in High‐Entropy Oxides

open access: yesAdvanced Science, EarlyView.
A generalizable strategy is developed leveraging facile anion‐lattice doping in high entropy materials to modulate the bandgap in high‐entropy metal oxides (HEMOs). By incorporating nitrogen into a single‐phase high‐entropy metal oxide/nitride (HEMO:HEMN) solid solution, a substantial bandgap reduction from 3.55 eV (HEMO) to ≈2.46 eV (HEMO:HEMN) is ...

Optimizing Polymer Composites for Effective Electromagnetic Shielding: The Role of Carbon Filler Properties and Temperature

open access: yesAdvanced Electronic Materials, EarlyView.
Polymer composites electromagnetic properties are promising for shielding applications. This study explores how filler geometry, orientation, and temperature impact shielding performance. Spherical carbon black enhances scattering, while anisotropic carbon nanotubes (CNTs) show directional wave propagation. CNT orientation critically affects efficiency,
