Figure 7
A creased piece of PET polymer formed nanocrystals along the fold lines. A radiograph (a) performed over the sub-region shown shows little contrast while the enhanced scattering into the q range of 0.03–0.04 Å−1 automatically generated from a series of SAXS measurements shows clear contrast of the fold lines (b).
