Abstract
The supramolecular rearrangements
of biopolymers have remained
difficult to discern. Here, we present a versatile approach that allows
for an <i>in situ</i> investigation of two major types of
rearrangements typically observed with cellulose, the most abundant
biopolymer on earth. Model thin films were employed to study time-resolved
pore size changes using <i>in situ</i> grazing incidence
small-angle X-ray scattering (GISAXS) during regeneration and drying
