Abstract

X-ray photoelectron spectroscopy (XPS) is a powerful tool that has been used to monitor the changes in chemistry on the surface of many materials. In this study it is used to examine the chemical changes in an epoxy system formulated with and without pigment (TiO2) after ultraviolet (UV) exposure to further explain the role of pigment in polymer degradation. The effect epoxy degradation as a function of surface treatment on the pigment and pigment concentration was also investigated. The individual components, the epoxy and pigment, will be analyzed separately in an effort to understand the changes observed for the entire system (pigmented epoxy). XPS results show that chemical changes have occurred on the epoxy surface and that the type of pigment does affect the extent of degradation. The concentration of pigment appears to have no effect on the extent of degradation.
