The supramolecular rearrangements of biopolymers have remained difficult to discern. Here, we present a versatile approach that allows for an 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 grazing incidence small-angle X-ray scattering (GISAXS) during regeneration and drying.
生物聚合物的超分子重排一直难以识别。在此，我们提出了一种通用方法，可用于研究纤维素（地球上最丰富的生物聚合物）通常出现的两种主要重排类型。使用模型薄膜，在再生和干燥过程中，通过掠入射小角X射线散射（GISAXS）来研究时间分辨的孔径变化。
