Anchored Fluoro‐Shielded Solvation for Lithium Metal Batteries

Advanced Materials, EarlyView.
Anchored fluoro‐shielded solvation reconstructs PVDF‐based polymer electrolytes by coupling polyanionic Li+‐solvate sites with fluorinated shielding segments. This design organizes anion‐rich solvation networks, strengthens selective Li+ transport, and generates LiF‐rich solid electrolyte interphase, enabling high conductivity, wide oxidative tolerance,

Light‐Controlled Localized Delamination and Blistering of Azobenzene‐Containing Polymer Thin Films in an Aqueous Environment

Advanced Materials Interfaces, EarlyView.
When exposed to light of a defined wavelength, the photoisomerization of azobenzene chromophores leads to polymer reorientation, generating stresses that result in solvent‐facilitated localized delamination of the film from the substrate. Additionally, blisters that form spontaneously when exposed to an aqueous environment can be manipulated via ...
