(a) Optical microscopy image of an 85 µm diameter hair deformed by microindentation using a load of 1000 mN at 100 mN s−1 for 10 s; (b) integrated SAXS intensity of the same region obtained using a 1 µm diameter beam with a scan step of 2 µm horizontally and 8 µm vertically; (c) image of the percentage shift in the peak position corresponding to the interfibrillar distance using the same scan parameters; (d, e) individual SAXS patterns taken, respectively, in an undeformed part of the fibre and in the vicinity of the deformed region indicated in (b) by upper and lower black pixels; (f) radial intensity profiles of the scattering patterns shown in (d) and (e), respectively, by the upper and lower curves, corrected for the scattering of the amorphous background; dotted lines indicate the peak shift to lower q values in the deformed region. |
