The photosensitivity resins which contain BYK®-307, EFKA®-3772, and BYK®-307+EFKA®-3772 respectively were UV cured under different atmospheres (air and N,2,). The surface properties of the cured films were characterized by means of surface energy measurement and X-ray photoelectron spectroscopy. The results show that the surface energy of the films with mixed probe components drops obviously, also the bonding energy of Si and F are changed obviously, and the difference is 0.4 eV and 2.13 eV, respectively. It indicates that the chemical environment can transform the result in the different surface energy of the films. Furthermore, the content of Si is high, whereas the content of F is especially low and even can’t be detected, which shows that it is easier for the segment with Si to migrate to the surface during the curing process.
