Linear‐Nonlinear‐Linear Sandwich‐Structured Polymer Composites With Metal‐Organic Framework (MOF)‐Enhanced Insulating Layers and Horizontally Oriented Nanotube‐Filled Polarization Layer for High Energy Storage Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A linear‐nonlinear‐linear (LNL) sandwich dielectric film was rationally designed for high energy storage. Its outer linear layers are MOF (ZIF‐8)‐enhanced PEI composites (EZ), and the middle nonlinear layer is an electrospun‐hot‐pressed P(VDF‐HFP)/TNTs composite (PT) with horizontally oriented TNTs.

Harnessing cracks in metal films: Design strategies for stretchable conductors

InfoMat, EarlyView.
In stretchable electronics, metal film‐based components function either as strain‐insensitive interconnects/electrodes or as strain‐sensitive sensors, both of which are governed by crack‐induced electromechanical responses, yet these two roles have often been discussed separately in previous reviews.
