Beyond Traditional Phenolics: Disulfide Bonds for Performance Enhancement of Aerospace Ablation‐Resistant Materials from Processing to Recycling

Advanced Science, EarlyView.
The dynamic disulfide bonds facilitated the development of high‐performance aerospace ablation‐resistant materials. At moderate temperature, the dissociation and recombination of disulfide bonds ensured excellent processability, mechanical properties, and recycling ability of phenolic resin; at high temperature, cleavage of disulfide bonds produced ...

Self‐Assembly of Organic–Inorganic Copolymers Toward Bio‐Inspired Cementitious Composites

Advanced Science, EarlyView.
Organic–inorganic copolymerization of calcium silicate hydrate and thioctic acid produces a self‐organized nanocomposite inspired by the disordered collagen–mineral architecture of trabecular bone. The resulting material combines a compressive strength above 300 MPa with intrinsic physical reprocessibility, retaining over 80% of its strength and energy

A Superstrong and Ultratough Stretchable Electronic Conductor With Ultradurable Strain‐Insensitive Electromechanical Performance

Advanced Science, EarlyView.
We report a superstrong, ultratough, and fatigue‐resistant stretchable electronic conductor (SEC) integrating a viscoplastic quasi‐solid LM‐Ag alloy with a supramolecular elastomer. Unlike conventional LM, the alloy exhibits thixotropic flow, reduced surface tension, and enhanced interfacial interactions with the elastomer.
