Boosting Ferroelectricity: 2D and Polymer Ferroelectric Hybrids Enabling Ambipolar Nonvolatile MoS2 Memory Transistor

Advanced Science, EarlyView.
Two‐dimensional CuInP2S6 nanosheets are incorporated into a P(VDF‐TrFE) matrix to induce polarization‐cooperative ferroelectric coupling. The resulting P(VDF‐TrFE)/CuInP2S6 hybrid film exhibits reinforced ferroelectric ordering and reduced coercive electric fields compared with pristine P(VDF‐TrFE).

Ionic Elastomer Interface for Low‐Pressure and Durable All‐Solid‐State Batteries

Advanced Energy Materials, EarlyView.
This work reports an ionically conductive elastomer that enables stable all‐solid‐state batteries（ASSBs）under low external pressure. The soft elastomeric matrix, integrated with a LiG3‐based conductive phase(lithium bis(trifluoromethanesulfonyl)imide and triethylene glycol dimethyl ether), simultaneously delivers high ionic conductivity and mechanical ...
