Modelling the 3D Structure of PEDOT:PSS Supramolecular Assembly in Aqueous Dispersion Based on SAXS with Synchrotron Light

In this work, we study the poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) structure in aqueous dispersion with small-angle X-ray scattering (SAXS). In-depth analysis is achieved based on a set of complementary and sophisticated algorithms, which provide not only shape packing chains but also 3D colloids. The information PEDOT chain was extracted from well-known Guinier, Porod pair distance distribution function (PDDF) SAXS data, while modelling DAMMIF DAMAVER programs ATSAS software package. To best our knowledge, first establish model PEDOT:PSS colloids’ that will help people to understand supramolecular assembly dispersion, sheds light solution polymers are widely used daily life.
