All‐Aqueous Pullulan Fibers Enabling Visible‐to‐Near‐Infrared Waveguiding with Mechanical and Thermal Resilience

open access: yesAdvanced Functional Materials, EarlyView.
Pullulan, a biomass‐derived polysaccharide, is transformed into transparent optical fibers using a solvent‐free borax hydrogel‐spinning method. The fibers outperform PMMA with ≈200 MPa tensile strength and 200 °C stability, while uniquely guiding visible‐to‐NIR light and enabling additive‐free humidity sensing.

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)

open access: yesAdvanced Functional Materials, EarlyView.
Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

A Hierarchically Structured, Stretchable, Anti‐Biofouling Encapsulation for Biodegradable Electronics

open access: yesAdvanced Healthcare Materials, EarlyView.
A soft, stretchable, anti‐biofouling encapsulant is developed by integrating organosilicon nanowire networks with microstructured biodegradable elastomers. The hierarchical surface exhibits superhydrophobicity and enhances water barrier properties by 420% over pristine polymers, while preserving mechanical integrity.
