제목 Eco-Degradable and Flexible Clay-DMSO Nano-composites as a Solid-State Ionic Conductor
초록 Solid-state electrolytes can alleviate the safety issues of chemical and thermal instabilities from liquid-state electrochemical systems. While a liquid provides seamless ionic transport between electrodes, a solid-state electrolyte needs to demonstrate comparable electrochemical performance to liquid electrolytes as well as mechanical robustness and flexibility. Here, we introduce the facile preparation of montmorillonite (MMT)/dimethyl sulfoxide (DMSO) nanocomposites, which show high ionic conductivities, mechanical strengths, and thermal stabilities by mimicking the layered structure of abalone shell. The mechanical strength with its molecularly confined structures and ionic conductivity at room temperature are confirmed by X-ray diffraction peaks, tensile test, and electrochemical impedance spectroscopy. Furthermore, its optical translucency and on-demand eco-degradability together make the composites unique materials with a wide range of solid-state electrochemical applications.
