Fig. 8: Structural analysis of spider draglien upon extension.

Two-dimensional WAXS profiles at strain rates of a 3.3 × 10−3 s−1, b 3.3 × 10−2 s−1, and c 3.3 × 10−1 s−1 using spider dragline silk fibers at RH43%. The simultaneous WAXS-tensile tests prevented us from making a composite image from the resultant WAXS data. Thus, the boundary of each camera detector remained in the overall scattering images because the single detector could not detect all the scattering of whole sample areas. The boundary of the camera detector is masked, which is highlighted by red lines.
