A novel 2D dual-layer step-like Janus array film (DSJAF) based on 1D Janus nanoribbon and Janus microfiber as structural units is devised and fabricated by combining conjugate with parallel electrospinning. In DSJAF, the top-layer Janus nanoribbon array film covers the left half of the bottom-layer Janus microfiber array film and the two films bind together to form the step-like composite film, achieving two sets of Janus structures, respectively, from top to bottom on the left half of the DSJAF and from left to right on the top surface of the DSJAF. The specially structured DSJAF exhibits two sets of double anisotropic conduction coming from the two sets of Janus structures, and single anisotropic conduction exists, respectively, in the top-layer film and bottom-layer film, realizing multiple anisotropic conductions. The conductive anisotropic degree of DSJAF is modulated by diverse structural units of Janus microfiber and Janus nanoribbon. Up-conversion luminescence (UCL) and ...

多个各向异性导电，上/下转换发光和磁性组装成二维阶梯状Janus阵列膜

通过结合共轭电纺丝和平行电纺丝技术，设计和制造了一种以一维Janus纳米带和Janus微纤维为结构单元的二维二维阶梯状Janus阵列膜（DSJAF）。在DSJAF中，顶层Janus纳米带阵列膜覆盖了底层Janus超细纤维阵列膜的左半部分，两层膜结合在一起形成阶梯状复合膜，从顶部分别获得了两组Janus结构在DSJAF的左半部分的底部，在DSJAF的上表面从左至右。特殊结构的DSJAF表现出来自两组Janus结构的两组双各向异性导电，并且在顶层膜和底层膜中分别存在单各向异性导电，实现了多个各向异性导电。DSJAF的导电各向异性程度受Janus超细纤维和Janus纳米带的不同结构单元调节。上转换发光（UCL）和...
