Improving adhesion and moisture permeability of UV/heat dual-curable adhesives using organic-inorganic hybrid resin

초록

Seamless displays have attracted considerable attention because they simultaneously offer an immersive experience and one virtual screen. In this study, we prepared new UV/heat dual-curable adhesives containing organic-inorganic hybrid resin for narrow bezel display. The silane coupling groups contained in the organic-inorganic hybrid resin react with substrates, thereby improving adhesion strength and reducing moisture permeability of adhesives. The UV/heat curing ratio, adhesive strength, moisture permeability, and internal contamination of new adhesive were compared with those of conventional sealant. The proposed adhesive offered high adhesion, reduced moisture permeability, and low internal contamination level for a full screen display application.
