Breathable Graphene Oxide‐Polymer Composite Membranes With Two‐Step Barrier Mechanism Against Nerve Agents

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Breathable membranes that reject chemical warfare agents (CWAs) are required for next‐generation protective apparel. A dual‐function graphene oxide (GO)‐polyamine architecture is introduced that addresses the long‐standing tradeoff between vapor transmission and CWA selectivity.

Uncovering the Origin of Efficiency Roll‐Off in TADF OLEDs

open access: yesAdvanced Functional Materials, EarlyView.
OLEDs based on thermally activated delayed fluorescent (TADF) materials often suffer from a severe drop in efficiency at high brightness levels. This work presents a technique to uncover the source of this efficiency drop, and quantifies the exciton‐exciton and exciton‐polaron annihilation processes responsible for efficiency losses in our TADF OLEDs ...

Robust Polymer Hydrogels Improve Electric‐Fish‐Inspired Batteries

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Electric‐fish‐inspired hydrogel batteries based on ion‐concentration gradients offer an attractive route to soft power sources; however, the poor mechanical properties of existing hydrogels limit device assembly and performance. Here, we report poly(ethylene glycol) methyl ether acrylate hydrogels that enable ion‐gradient batteries composed of
