Li_xNa_2-xW₄O₁₃ nanosheet for scalable electrochromic device.

ABSTRACT: The printed electronics technology can be used to efficiently construct smart devices and is dependent on functional inks containing well-dispersed active materials. Two-dimensional (2D) materials are promising functional ink candidates due to their superior properties. However, the majority 2D materials can disperse well only in organic solvents or in surfactant-assisted water solutions, which limits their applications. Herein, we report a lithium (Li)-ion exchange method to improve the dispersity of the Na₂W₄O₁₃ nanosheets in pure water. The Li-ion-exchanged Na₂W₄O₁₃ (Li_xNa_2-xW₄O₁₃) nanosheets show highly stable dispersity in water with a zeta potential of -55 mV. Moreover, this
