제목 Preparation of dual curing adhesive with improved mechanical properties
초록 We prepared a dual curing adhesive, consisting of thiol/acrylate/epoxy, with improved adhesion strength. The thiol-acrylate reaction was carried out through photo-curing system, whereas the thiol-epoxy reaction occur in the thermal-curing system. The reaction was achieved using a thiol with 4 functional groups, an acrylate with 2 or 3 functional groups, and an epoxy with 2 functional groups. The structure of the synthesized adhesive was confirmed at each stage of the curing process by FT-IR spectroscopy. The lap-shear and peel strength of the dual-cured adhesive between 2 PC film was measured using a universal testing machine. Furthermore, photo-differential scanning calorimeter was used to confirm the thermal characteristics. The gel fraction was measured to confirm the cure degree of adhesives. Viscosity was also measured for 3 days to check storage stability of adhesives.
