Double Anisotropically Electrical Conduction Flexible Janus-typed Membranes

Abstract

Novel type III anisotropic conductive films (ACFs), namely flexible Janus-typed membranes, were proposed, designed and fabricated for the first time. The flexible Janus-typed membranes composed of ordered Janus nanobelts were constructed by electrospinning, which simultaneously possesses fluorescence and double electrically conductive anisotropy. For the purpose of fabricating the Janus-typed membrane, Janus nanobelt comprising a conductive side and an insulative-fluorescent side is primarily fabricated, and then the Janus nanobelts are arranged into parallel array by using an aluminum rotary drum as collector to obtain a single anisotropic conductive film. Subsequently, secondary electrospinning process is applied on the basis of the as-prepared single anisotropically conductive film to acquire the final Janus-typed membrane. For this Janus-typed membrane, namely left-to-right structure, anisotropically electrical conduction synchronously exists on the both sides, and furthermore, the two electrically conductive directions are perpendicular. By modulating the amounts of the Eu(BA)3phen complexes and conducting polyaniline (PANI), the characteristics and intensity of fluorescence-electricity dual-function in the membrane can be tuned. The high integration of the peculiar Janus-typed membrane with simultaneous double electrically conductive anisotropy-fluorescent dual-functionality is successfully realized in this study. This design philosophy and preparative techniques will provide supports for devising and constructing new-typed special nanostructures of multi-functionality.
