Electrospun Flexible Janus Nanoribbons Array Endowed with Simultaneously Tuned Trifunctionality of Electrically Conductive Anisotropy, Photoluminescence and Magnetism

Abstract

Novel structured {[Dy(BA)3phen+Eu(BA)3phen]/PMMA}//[PANI/Fe3O4/PMMA] Janus nanoribbons array possessing tunable anisotropically electrical conduction, photoluminescence and magnetism has been triumphantly prepared by electrospinning technology with a parallel spinneret. Every single Janus nanoribbon is comprised of PANI, Fe3O4 NPs and PMMA as a conductive and magnetic side, and Dy(BA)3phen, Eu(BA)3phen complexes and PMMA as an insulating and photoluminescent side. The emitting color of the Janus nanoribbons array excited by 275-nm ultraviolet light could be oriented in an extensive range of yellow-orange-red color by modulating the contents of rare earth complexes, PANI or Fe3O4 NPs. Furthermore, electrically conductive anisotropy of Janus nanoribbons array can be tunable by modulating PANI content, and the conductance ratio between parallel and perpendicular to the length direction of Janus nanoribbons in array can be varied from 104 to 106. The conductances in the parallel and perpendicular direction of the Janus nanoribbons array containing 60 % of PANI are about 1.8246×10-4 S and 1.438×10-10 S, respectively. Besides, the magnetic performance of Janus nanoribbons array could also be tunable by modulating quantities of Fe3O4 NPs. Additionally, fabrication means for the Janus nanoribbons array is of widespread significance for fabricating else anisotropically conductive films with multi-functionality.
