Exceptional Elasto‐Dielectric Properties in a Highly Flexible Dielectric Elastomer Composite: The Key Roles of Parallel Elastic Nanofibers

Advanced Materials Technologies, EarlyView.
Soft dielectric elastomer composites often face a trade‐off between enhanced dielectric properties and mechanical compliance. Here, a parallel‐aligned polyurethane nanofiber network embedded in PDMS creates a flexible, durable composite with increased permittivity, low modulus, and fatigue stability after 100,000 cycles.

Linking Polyelectrolyte Modification and Enzyme‐Catalyzed Phenolic Acid Functionalization of Cellulose Fiber for Functional Foams

Advanced Materials Technologies, EarlyView.
Cellulose fibers functionalized using cationic poly(Dimethyldiallylammonium chloride) (polyDADMAC) and laccase‐mediated ferulic acid system are processed into foams using different surfactants (Anionic, cationic, and non‐ionic). Fiber–surfactant interactions influence foam stabilization and porous structure formation during convective drying, producing
