With respect to the exposed and redoped films, in-plane line-cuts from dedoped film GISAXS scattering patterns displayed a decrease in intensity of the scattering feature and a shift to higher q-vector, bringing it more in line with the as prepared scattering data (Figure ). The intensity decrease is ascribed to suppression of the electron density contrast between the crystalline nanofibrillar domains and the inter-fibrillar voids/domains due to the ion reorganization (cation accumulation within the nanofibrils) that accompanies dedoping, while the shift to higher qvector as reflects an expansion of the inter-fibrillar voids/domains as the nanofibrils contract (Figure ).
