XPS Surface Characterization of UV Photo-Oxidized Colorless Polyimides
Source abstract
Abstract
The colorless polyimides LaRC™-CP1 (6FDA–1BDAF) and LaRC™-CP2 (6FDA–APB), which are frequently used in the aerospace industry, were exposed to UV photo-oxidation at atmospheric pressure. XPS data show a significant increase in the oxygen concentration and decrease in the carbon concentration as a result of treatment. There are slight, but significant, increases in the concentrations of nitrogen and fluorine as a result of treatment indicating ablative degradation of low molecular weight carbon-containing compounds. The increase in the concentration of oxygen appears to be primarily due to the O=C–O moiety.
