Abstract Scope |
Thermal transport across interfaces has been widely identified as the critical technical bottleneck in thermal management and thermal energy conversion. The “ideal” thermal interface materials must simultaneously possess high thermal conductivity for minimizing thermal resistance, and high flexibility and compliance for adapting to soft and curved surfaces and accommodating the thermal stress derived from the mismatch of thermal expansion between two jointed materials. Here we demonstrate new types of nanostructured thermal interface materials that can thermally bridge the interfaces with ultra-low thermal resistance and mechanical compliance. Compared with the state-of-the-art thermal interface materials, the nanostructured thermal interface materials demonstrate low thermal resistance and polymer-like compliance. With the significantly enhanced heat transfer and compliance, these nanostructured thermal interface materials can greatly benefit flexible electronics, microelectronics, and thermal energy converters by allowing the systems to achieve high performance and high power. |
