Paper Abstract

A method using UV-curable epoxy resin is described to modify organic polymer substrates without changing the bulk properties of substrate material. The reagents contain an acrylate or other photoactive group which, when exposed to light of appropriate wavelength, generates highly reactive intermediates that covalently bond with nearly any organic material. Applying epoxy resin onto the surfaces of such materials, the surface properties can be modified to achieve greatly increased bond strengths with conventional adhesives. Flexible organic light-emitting diode (FOLED) is fabricated on indium-tin oxide (ITO) plastic substrate by inserting a UV-curable epoxy resin as a buffer layer between plastic substrate and ITO film. A maximum luminance of FOLED of 4,860 cd/m2 at 12 V is obtained.
