| Abstract | Changes in surface characteristics of phenolphthalein poly(ether sulfone) (PES-C) film induced by ultraviolet (UV) irradiation were investigated. The surface properties of the pristine and irradiated films were studied by attenuated total-reflection FTIR (FTIR-ATR), X-ray photoelectron spectroscopy (XPS), contact anglemeasurements and atomic force microscopy (AFM). Itwas found that photooxidation degradation took place on the sample surface after irradiation and the oxygen content in the surface increased as evidenced byFTIR-ATRandXPSresults. The water contact angle of the irradiated films decreased with increasing irradiation time, which was ascribed to the increased polarity of the surface induced by photooxidation. The etching of ultraviolet irradiation induced the roughening of PES-C surface after irradiation with its root-mean-square roughness (RMS) determined by AFM increased from 2.097 nm before irradiation to 7.403 nm in the area of 25 μm × 25 μm. |
