Abstract

Silicone-coated polycarbonate was photochemically modified into SiO2 by a 157-nm fluorine laser for developing an automotive resin window to satisfy United Nations Economic Commission for Europe (UNECE) regulations for the abrasion resistance of ΔH1000≦2%. We considered a mesh mask. With it, we improved the abrasion resistance by increasing the laser irradiation time to less than 30 s; by increasing the laser irradiation, the abrasion resistance decreased. We revealed that abrasion resistance can be suppressed by lowering the opening length of the mesh mask using laser irradiation through it. By suppressing the stress caused by the photochemical modification by setting the distance between the mesh mask and the sample surface, good abrasion resistance less than 2% was obtained for any laser irradiation time at 20 mm.
