Molecularly Engineered Ultralow‐Loss Soft Polymers for Deformable Printed Photonics

ABSTRACT Achieving ultralow optical loss, broadband transparency, and mechanical softness within a single polymer network remains a long‐standing challenge for soft photonics. Here, we report a molecularly engineered class of UV‐curable thiol‐ene‐aromatic polymers that reconciles...

Engineering Hidden Ferroelectric‐Like Distortion for Ultralow Thermal Conductivity in Polar van der Waals Tetradymite

ABSTRACT Ferroelectric‐like polar structures enable diverse functionalities through coupling with charge and phonon transport. Although effective in modulating thermal conductivity, the rational design of novel polar materials with intrinsically low thermal conductivity via ferro...
