Flexible transparent electrodes have drawn increasing interest due to the rapid development of flexible electronics and sensors. Metal networks is an emerging novel transparent electrode, which has shown potential applications in organic electronics and wearable sensors. However, the techniques which can realize facile fabrication of non-transfer, large-area and low-roughness metal-network are desperately desired. Our work demonstrates a print-compatible method for fully interconnected metal networks directly on the flexible substrate. We use blade-coat process to create polymer-sphere networks on the flexible substrate and then convert them into polymer networks. We combine evaporation process to transfer the networks into interconnected metal structures on the substrate. We demonstrate such transparent electrodes as the top electrodes both in the spin-coat and printed polymer photodiode and light emitting diode. This technique is low-cost, print compatible and can achieve the low-roughness and large-area transparent electrodes directly on the flexible substrate, which shows potential applications in large-area organic electronics.
