Composites of liquid metal particles dispersed within elastomer. a) Photograph of a soft, flexible, and stretchable liquid metal elastomer composite. Scale bar is 10 mm. Adapted with permission.[ 143 ] Copyright 2016, Wiley‐VCH. b) These composites are stretchable, easy to process and provide enhanced thermal conductivity yet often remain electrically insulating. Reproduced with permission.[ 148 ] Copyright 2015, Nature Publishing Group. c) Flexible liquid metal elastomer composite can dissipate heat quickly, demonstrating a high thermal conductivity. Scale bar is 25 mm. Adapted with permission.[ 149 ] Copyright 2017, National Academy of Sciences. d) Morphology of liquid metal elastomer under 0%, 100%, 200%, 300%, and 400% strain illustrates how the liquid particles align with strain and thereby affect thermal conductivity. The images are taken under an optical microscope. Scale bar is 25 µm.
