Full Solution-Processed Fabrication of Conductive Hybrid Paper Electrodes for Organic Optoelectronics

摘要： There is growing interest in the development of “green” electronics fabricated from “natural” materials, which could lead to renewable, sustainable and potential inexpensive organic optoelectronics. In this paper, a novel, facile and full-solution processed approach has been successfully demonstrated to fabricate a highly flexible and conductive paper electrode by electroless deposition with the dopamine molecules as an adhesion layer on the newly hybrid paper. The novel paper substrate was prepared through simple hot-press with commercial paper and polypropylene (PP) film. And it has smooth surface and improved mechanical property. Importantly, it is flexible and highly resistant to water, which was important for solution process. The obtained highly conductive paper exhibited smooth and hydrophobic surface with high reflection. In addition, these conductive papers also showed excellent mechanical flexibility and stability, indicating the strong adhesion between metal and hybrid paper, which facilitates the roll-to-roll process of the device. As a possible application, this paper electrode can be effectively used as a mechanical support and electrode in organic light-emitting diode (OLED), showing the potential possibility in future electronics.
