摘要

•3D tubular structured PDMS was produced by a coaxial direct ink writing technique.•3D core-shell structure was obtained by incorporating liquid metal into t-PDMS.•The EGaIn core and PDMS shell make the composite highly stretchable and conductive.•Exceptional and strain-tolerant EMI shielding performance was achieved.
