Construction of Semi-Bianisotropic Conductive Janus-Structure Membrane Offering Magnetism and Fluorescence by Utilizing Different Functional Blocks

A new concept of semi-bianisotropic conductivity is put forward based on modularization design. Half of the material has dual anisotropic conductivity while the other half has single anisotropic conductivity by adjusting areas of the two surfaces endowed with anisotropic conductivity and vertically arranged up to down. Semibianisotropic conductive Janus-structure membrane affording magnetism and fluorescence (SCMF) is prepared by constructing three blocks via electro-spinning. Three blocks, including C-R block (top), M-G block and C-R block (down), are assembled into SCMF. Janus-structure nanobelts are selected as building units to gain micro zoning. Modular structure further prevents negative interactions among various functional substances. SCMF has bicolor luminescence and variable magnetism. SCMF gains tuned semi-bianisotropic conductivity, where the area of C-R block (top) with single conductive aeolotropism is half of C-R block (down) with single conductive aeolotropism, so half of SCMF has double conductive aeolotropism and other half of SCMF has single conductive aeolotropism.
