Abstract

The supramolecular rearrangements of biopolymers have remained difficult to discern. Here, we present a versatile approach that allows for an in situ 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 in situ grazing incidence small-angle X-ray scattering (GISAXS) during regeneration and drying.
