From: Fully solution processed liquid metal features as highly conductive and ultrastretchable conductors
a XPS spectra acquired from each critical step to achieve electroless deposition of Cu film on SEBS substrate. b Contact angle images of liquid metal droplets on pristine and Cu-covered SEBS substrates before (left) and after (right) treatment in dilute HCl. Scale bar: 1 mm. c XRD spectra acquired from electroless plated Cu film (red) and liquid metal pattern (black).
