Upcycling Keratin‐Based Textile Waste Into High‐Performance Hybrid Fibers Via Tuning the Interfacial Interactions

Advanced Functional Materials, EarlyView.
Keratin recovered from animal‐hair textile waste is fractionated and blended with cellulose to produce continuously spun hybrid fibers. Selecting the high‐molecular‐weight keratin fraction enables 30 wt.% keratin incorporation while maintaining high strength in dry and wet states.

Synergistic Integration of Liquid Crystalline Ordering and Dynamic Networks for Ultrarobust Bismaleimide Vitrimers

Advanced Functional Materials, EarlyView.
A liquid‐crystalline bismaleimide vitrimer integrates local mesogenic organization with exchange‐active ester connectivity, achieving a glass‐transition temperature near 300°C while remaining reprocessable. Stress‐relaxation analysis and temperature‐dependent remolding reveal how segmental mobility, network rearrangement, and structural integrity ...

Closed-loop recycling of tough epoxy supramolecular thermosets constructed with hyperbranched topological structure

Nature Communications
The regulation of topological structure of covalent adaptable networks (CANs) remains a challenge for epoxy CANs. Here, we report a strategy to develop strong and tough epoxy supramolecular thermosets with rapid reprocessability and room-temperature ...

Acetoacetates Derived From Vegetable Oils: A Platform for Tailor‐Made Vinylogous Urethane Foams

Advanced Functional Materials, EarlyView.
A renewable vegetable oil is converted into acetoacetate‐functionalized precursors for the preparation of catalyst‐free vinylogous urethane foams. Room‐temperature foaming with n‐pentane generates lightweight cellular materials, while the choice of amine enables control over foam structure and mechanical properties.

Switching between Non-isoenergetic Dynamic Covalent Re-actions using Host-guest Chemistry [PDF]

CO2 reacts with simple amines in presence of water to generate dynamic combinatorial libraries of majority (i.e., am-monium carbamates) and minority (i.e., ammonium carbonates) non-isoenergetic covalent adducts.
