Multi-Scale Bionic Structure Constructs Biomass Flame-Retardant Thermal Insulation Foam Material. [PDF]
Adv Sci (Weinh)Inspired by mussel adhesion and hierarchical brick‐and‐mortar architectures, a cellulose‐based biomimetic foam is constructed by anchoring bentonite nanosheets onto a polydopamine‐decorated cellulose nanofiber network. The resulting foam combines low thermal conductivity with intrinsic flame retardancy and full biodegradability, presenting a ...

Hydrogen-Bond Enabled Phosphite Based Intrinsic Flame-Retardant Solid-Solid Phase Change Materials Using Catalyst/Solvent-Free Multi-Component Reaction for Battery Thermal Management. [PDF]
Adv Sci (Weinh)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%,
