| Abstract: | In the present study, the pretreatment of glass-epoxy resin using photoreaction of TiO2 sol prepared by hydrothermal method was investigated. The surface properties for the pretreated substrate were examined, and the change of contact angle was measured to confirm the hydrophile property caused by the photocatalytic reaction. After the pretreatment, the surface was oxidized with showing no changes in its morphology. However, the surface roughness at nano-scale order increased with the photocatalytic reaction time. When UV light was irradiated for 60 min in TiO2 sol, the adhesion strength of electroless-plated Cu film was most excellent in other test conditions. |
