Fig. 1 Two-dimensional, hierarchically buckled sheath-core fibers. Two-dimensional, hierarchically buckled sheath-core fibers. (A) Steps in the fabrication of an NTSm@fiber. The circular arrow indicates the belt direction. (B) Illustration of the structure of a longitudinal section of an NTSm sheath, showing two-dimensional hierarchical buckling. The fiber direction is horizontal. The yellow color in (A) and (B) represents SEBS rubber; the gray shells are NTS layers. (C and D) Low- and high-resolution SEM images showing long- and short-period buckles for an NTS180@fiber at 100% applied strain. The fiber direction, which is the direction of the applied strain, is horizontal and the belt direction is vertical. The fabrication strain was 1400%. Z. F. Liu et al.
