Foldable and flexible electronics are not only a very important but also a promising issue for the convenient transportation and diverse deployment of large area electronics. In this presentation, improved uniformity and printability of the flexible multilayered films fabricated on the surface of commercial paper substrates are illustrated. Due to the lack of transparency for this paper-based substrate, top-emitting organic light emitting diode (OLED) was employed, where its light emitting behavior and efficiency was investigated in terms of the multilayer surface composition on paper and functionality.Moreover, in order to realize a foldable and deformable display, printed circuits should be also robust under repeated operation. The graphenenanoplate-based circuits, prepared on the paper substrate by simple transfer printing, showed a small change in conductance under various folding anglesretaining more than 80% of initial conductance. Our approach will be a facile and cost-effective strategy for foldable and flexible OLEDs toward application at disposable electronics and digital signage. |
