Abstract
An effect of ultraviolet exposure over the inhomogeneous structure of ionomer was investigated by using small-angle X-ray scattering (SAXS). Ionomer sheet laminated in between two sheets of glass was artificially weathered using a xenon lamp in an Atlas Ci4000 weatherometer. Though no significant changes were detected by chemical, thermal and optical analysis approach, SAXS identified changes at a low-angle upturn in the region of q < 0.01 Å−1 (where q is the magnitude of the scattering vector) after xenon light irradiation. Power law, I ∼ q−α, was employed to study the changes in the upturn and found α changed from 3.0 to 1.7, indicating a change in the micron-sized X-ray scatterers. A relationship between differences in the low-angle upturn and the inhomogeneous structure is interpreted as a rearrangement of cation distribution induced by xenon light irradiation.
