["The rapid growth of flexible electronics has led to significant demand for relevant accessories, particularly highly efficient flexible heat dissipators. The fluidity of liquid metal (LM) makes it a candidate for realizing flexible thermal interface materials (TIMs). However, it is still challenging to combine LM with a conductive thermal network to achieve the synchronous improvement of thermal conductivity and flexibility. In this work, highly conductive flexible LM@GN/ANF films are made by coating LM nano-droplets with graphene nanosheets (GN) via sonication, and then they are combined with aramid nanofibers (ANF). The LM@GN/ANF film is found to have a thermal conductivity of 5.67 W m-1 K-1 and a 24.5% reduction in Young's modulus, making it suitable for various flexible electronic applications such as wearable devices and biosensors.","LM nano-droplets are coated by GN, enhancing the binding of LM and ANF and the stability of LM nano-droplets. LM@GN form a uniformly distributed thermal conductive network, achieving a thermal conductivity of 5.67 Wm-1K-1. The deformability of LM and the interaction between GN and ANF improve the flexibility of the film, resulting in a 24.5% decrease in Young's modulus. image"]
