The silane-capped polyurethane acrylate (sPUA) was synthesized using polycaprolactone diol, isophrone diisocyanate, 2-hydroxyethyl methacrylate, and 3-aminopropyl triethoxysilane. The UV-curable sPUA based adhesive was obtained with sPUA oligomer, acrylic diluents (2-hydroxyethyl acrylate and 1,6-hexanediol diacrylate), and 1-hydroxycyclohexyl phenyl ketone as a photoinitiator. The structure of sPUA was characterized by fourier transform infrared spectroscopy analysis. The transmittance and the yellowness of the cured sPUA based adhesive was similar to that of the PET film. As the photoinitiator content increased, the adhesion strength between PC/PC films and between Ag-PET/Ag-PET films also increased. The image of transfered Ag nano particle to PC film was observed well regardless of the photoinitiator content. The sheet resistance of the transferred Ag nano particle was measured using a multimeter. The ranges of sheet resistance values were 30-60 Ω/□.
