Hierarchically Buckled Sheath-Core Fibers

Caption

Two-dimensionally, hierarchically buckled sheath-core fibers are shown. A) An elastic conducting fiber is fabricated by wrapping carbon nanotube sheets around a stretched rubber core. B) Illustration of the hierarchical buckles that form in the nanotube sheath when the stretch is partially released from the 1400% strain applied during fabrication. C) and D) Scanning electron microscope images of the buckling for a sheath-core fiber that is oriented horizontally.
