FIGURE 7.

Synthetic fibers spun from purified recombinant AgSF1 contain amorphous domains. A, XRFD two-dimensional pattern of a single as-spun AgSF1 fiber. B, XRFD two-dimensional pattern of the AgSF1 synthetic fiber after 3.5 × post-spin draw treatment. C and D, one-dimensional radial intensity profile of the azimuthally integrated, whole two-dimensional pattern from the as-spun and 3.5 × post-spun fibers, respectively. E and F, one-dimensional azimuthal intensity profile of the radially integrated diffraction rings at d ∼ 4.5 Å and 10 Å for the as-spun and 3.5 × post-spun fibers, respectively.
