Polyimide/graphene oxide nanoribbon (PI/GONR) composite fibers were prepared by wet spinning. The unfolded GONRs by the intense drawing of fibers maximized their contribution to enhance mechanical and conductivity properties. The composite fibers were spun with an optimal drawing ratio of 18, follow...
