SAXS profiles of PET film treated with Fast-PETase for different reaction times. The degradation experiment was independently conducted to obtain data for (A) (earlier stage of degradation) and (B) (later stage). A Lorentz-factor-corrected plot (q – q² ∙ I plot) is also shown in the inset of Panel (A); arrows indicate the peak maxima for the films degraded for 0 h and 4 h. The scattering profiles in B were prepared by merging the WAXD data with SAXS data as described in Section “Small-angle X-ray scattering (SAXS) and wide-angle X-ray diffraction (WAXD)”. The data acquired after 68.8 h of degradation were fitted (closed circles in Panel B) and followed a power law with an exponent of −3.2 along the scattering vector q, as shown by the black line
