Ionic liquids have shown promising applications in the fields of micro-nanoelectronic devices and electrochemistry due to their unique thermal and electrical properties. Tailoring interfacial thermal conductivity at the nanometer scale through controllable preparation of ionic liquids is the key issue that must be addressed in its large-scale application. We propose that two-dimensional ionic liquids (2D-ILs) can be used to regulate the interfacial thermal conductivity through the change of the structural order. In our project, anti-solvent method will be adopted to prepare 2D-ILs by controlling the moving of the three-phase (gas-liquid-solid) contact line and interfacial thermal/mass transfer. Force regulation will be used to modify the structure of 2D-ILs and hence decrease the interfacial thermal resistance between 2D-ILs and substrates. New detection techniques will be developed to characterize the multi-scale structures of 2D-ILs, combined with the analysis of evolution dynamics of the cooperative forces involved in the self-assembly process and interfacial mass transfer, the formation and regulation mechanism of 2D-ILs will be elucidated. This project will lay a foundation for the application of ILs in the field of interfacial thermal transport and provide new ideas and new methods for the development of ILs in surface reactions including electrochemical and catalytic processes.
