UV curable PUA was synthesized using PCLD, IPDI, a mixture HEMA and 3-aminopropyl triethoxysilane as chain capping agent. We prepared PUA based adhesive by mixing HEA and HDDA as acrylic diluents. Silver nanoparticles are randomly patterned on PET film and they are organically connected. We investigated the effect of adhesive viscosity and thickness on the transfer level of silver nanoparticles on PET film to PC film. The viscosity of the adhesive was confirmed to be a major factor in enclosing the silver nanoparticles stacked at a certain height on the PET. It was confirmed that the thickness of the adhesive should be higher than the thickness of the silver nanoparticles on the PET. As a result, the silver nanoparticles transfer to PC film has a smooth surface, transparency and excellent electrical properties by optimum adhesive viscosity and thickness. The cured PUA based adhesive was analyzed for 4 point probe resistivity, transfer image and adhesion strength between PC/PC films. |
