Stretchable and Leakage‐Free Liquid Metal Networks for Thermal Management
Sichuan University · Nanjing University of Aeronautics and Astronautics
Abstract
Abstract Stretchable thermally conductive materials (TCMs) are highly desirable for efficient thermal management in wearable electronics. However, yielding stretchable TCMs that can simultaneously achieve superior thermal conductivity (TC) and high stretchability remains challenging owing to the contradiction between their thermal and mechanical behaviors. Herein, the design of a bi‐continuous structure that enables the creation of highly stretchable composites by incorporating liquid metal (LM) within a thermoplastic urethane (TPU) framework, is reported. The continuous TPU framework acts as a load‐bearing skeleton to ensure stretchability, while the LM forms 3D continuous thermal network, providing…
