Ultra‐Robust Conductive Hydrogels Enabled by a Gradient Bond‐Breaking Pseudo‐Drying Strategy

open access: yesAdvanced Science, EarlyView.
A bioinspired PVA‐ANFs hydrogel, engineered via novel gradient bond‐breaking, achieves unprecedented mechanical performance: ultrahigh strength (≈18 MPa), modulus (≈12 MPa), toughness (≈74 MJ/m3), and record fracture energy (≈269 kJ m−2). It exhibits cryogenic flexibility (−70°C), high ionic conductivity (936.3 mS m−1), and biocompatibility.

Volumetric Additive Manufacturing of Dormant Catalytic Chemistries to Generate Silicone Micro‐ and Millifluidic Devices and Instant Molds

open access: yesAdvanced Science, EarlyView.
We describe use of a novel zero‐dose approach to tomographic volumetric additive manufacturing that has enabled us to print silicone micro‐ and millifluidic devices and instant molds within minutes. The silicones are polymerized using photoactivated dormant platinum photohydrosilylation catalysts that would traditionally be difficult to access in ...

Laser‐Engraved Micro‐Patterned rGO/WPU Composite Structures for Aircraft Applications: Synchronizing Electrothermal De‐Icing and Broadband Microwave Transparency

open access: yesAdvanced Science, EarlyView.
While conventional electrothermal materials tend to reflect electromagnetic waves during de‐icing. Inspired by the frequency‐selective surface theory, this paper designs NJPS for rGO/WPU electrothermal coatings based on the traditional Jerusalem structure.
