Flexible Carbon-Based 3D Conductive Network Structure Blade-Coated on Poly(ethylene terephthalate) Substrate for Light-Emitting Electronic Devices

摘要

Herein, the blade-coated conductive ink on poly(ethylene terephthalate) substrate with unique features is demonstrated, aiming at the fabrication of flexible light-emitting electronic devices. The inks are prepared by combining carbon-based fillers and epoxy resin to achieve a high-performance 3D conductive channel network with low resistance. The carbon-based channels in the conductive composites withstand 2000 bending-releasing cycles (bending radius of 10 mm); excellent resistance reliability with the value of R/R (0) is 1.059. Moreover, carbon-based epoxy composites also possess a mechanical fastness under ultrasonic treatment and chemical durability to various organic solvents and have an excellent performance in the application of light-emitting electronic devices. Here, this work provides a new solution for the development of high-efficiency, low-cost, large-scale production of flexible electronics.
