Abstract

Flexible quantum dot light emitting diodes have attracted widespread attention due to their many advantages such as low cost, color tunability, and high luminance effciency. Among flexible electrodes, copper nanowires have attracted much attention due to their high electrical conductivity, simple fabrication process, and low cost. However, the oxidation and poor film quality of copper nanowires films are the barrier that restrict their practical application. In this paper, polyethylene terephthalate/copper nanowires/poly(p-phenylene benzobisoxazole) composite flexible electrode can solve the problems of oxidation and high surface roughness of copper nanowires, which improves the performance of flexible quantum dot light emitting diodes.
