Abstract

This paper investigates thermal transport in a nanocomposite system consisting of a porous silicon matrix filled with ionic liquid. Firstly, the thermal conductivity and heat capacity of two imidazolium and one ammonium ionic liquids were evaluated using the photoacoustic approach in piezoelectric configuration and differential scanning calorimetry, respectively. Then, the thermal transport properties of the composite system "ionic liquid confined inside porous silicon matrix" were investigated with the photoacoustic approach in gas-microphone configuration. The results demonstrated a significant enhancement of the thermal conductivity of the composite system when compared to the individual components, i.e. (i) more than two times for pristine porous silicon and (ii) more than eight times for ionic liquids. These results provide new paths for innovative solutions in the field of thermal management, particularly in the development of highly efficient energy storage devices.

摘要

本文研究了由多孔硅基质填充离子液体组成的纳米复合材料系统中的热传递。首先，使用压电配置的光声法和差示扫描量热法评估了两种咪唑鎓和一种铵离子液体的热导率和热容。然后，使用气体-麦克风配置的光声法研究了“离子液体限制在多孔硅基质内”的复合体系的热传输性质。结果表明，与单个组件相比，复合体系的热导率有了显著提高，即（i）对于原始多孔硅提高了两倍以上，（ii）对于离子液体提高了八倍以上。这些结果为热管理领域的创新解决方案提供了新途径，特别是在高效储能器件的开发方面。
