The cupric-ion adsorption effects on the nano-scale structures of the ultraviolet (UV) light irradiated poly(acrylamide/sodium acrylate) gels have been investigated by the small angle X-ray scattering (SAXS) measurements. It has been revealed that, without the cupric ion adsorption, the UV-light irradiated PAAm/SA gels do not show any characteristic structures in the SAXS profiles while a distinct peak has been observed in each of the SAXS profiles of the Cu-adsorbed gels; the SAXS peak position and width become smaller with the UV-light irradiation period indicating the development of the chelating aggregation of the network polymers of which the interconnections are progressively cut off with the UV-light dosage.
