【 摘 要 】
Ga-Based thermal interface material (TIM) pads/sheets with high thermal conductivity ($\kappa$) are indispensable components in thermal management systems. Here, we present a feasible method to fabricate heat conduction pads, which are composed of carbon nanotubes embedded into a liquid metal (LM). This setup has resulted in a large increase of $\kappa$ reaching $\sim$14.2 W mK$^{−1}$, greater than that of most of the commercial thermal silicone pads ($\sim$5 W mK$^{−1}$). In addition, a series of experiments were conducted on smartphones to evaluate the heat dissipation performance of the CPU. It turned out that LM/nanotube pads with TIMs show distinguish thermal conductivity performance.
