摘要

Laser scanning confocal microscopy (LSCM) has become a powerful tool for monitoring physical changes in polymeric coatings following ultraviolet (UV) radiation exposure. Physical changes caused by UV exposure include film ablation, formation of pits and other surface defects, and increases in surface roughness. Physical changes as a function of exposure time were compared to chemical degradation measured with Fourier Transform Infrared (FTIR) spectroscopy. It was found that after 400 h of UV exposure, film thickness changes measured by LSCM were not correlated to the thickness predicted by chemical degradation in an acrylic urethane coating. Local physical changes (pit formation and surface deformation) were observed that might contribute to chemical changes.
