Hydrogen‐Bond Enabled Phosphite Based Intrinsic Flame‐Retardant Solid‐Solid Phase Change Materials Using Catalyst/Solvent‐Free Multi‐Component Reaction for Battery Thermal Management

Advanced Science, EarlyView.
The phosphite group endows intrinsic flame retardancy, while the P = O bond enhances intermolecular interactions to realize solid‐solid phase transition. Battery thermal management tests show the materials extend the safe working time of lithium‐ion batteries by 200%. Cone calorimeter tests indicate a 14s delay in ignition time, and reductions of 37.6%,

Synthesis of Ladder and Flexible Polysulfonimides Directly From Anionic Monomers: Investigating Structure–Property Convergence in Succinonitrile–Polymer Electrolyte Blends

Angewandte Chemie, EarlyView.
Direct synthesis of sulfonimide‐based polymers of intrinsic microporosity enables comparison with compositionally similar flexible analogs. Incorporation of a common pore‐filling transport medium drives these fundamentally different polymer architectures toward similar bulk conductivity and mechanical properties while revealing distinct microscopic ion‐

Architected Spatially Deterministic Multiscale Phase Segregation in Block Copolymer Composites for Augmented Radiative Cooling

Advanced Science, EarlyView.
Multiscale phase segregation in block copolymers enables spatially deterministic structuring from molecular to macroscopic scales, decoupling solar scattering and infrared emission for augmented radiative cooling. ABSTRACT Passive radiative cooling, which reflects solar irradiation while emitting heat through the atmospheric window, provides a ...
