Summary:Ga-Based thermal interface material (TIM) pads/sheets with high thermal conductivity ( κ ) 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 κ reaching ∼ 14.2 W mK - 1 , greater than that of most of the commercial thermal silicone pads ( ∼ 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.
