2D dual anisotropic conductive left‐to‐right structured special Janus array pellicle (SJAP) synchronously functionalized by red‐green two‐colored fluorescence and magnetism was constructed by electrospinning. SJAP is assembled by two closely joint films, viz. {[CoFe₂O₄/polymethylmethacrylate (PMMA)]@[polyaniline (PANI)/PMMA]}//[Tb(acac)₃bipy/PMMA] special Janus nanostrip array film as left‐side (L‐SJAF) and {[CoFe₂O₄/PMMA]@[PANI/PMMA]}//[Eu(TTA)₃(TPPO)₂/PMMA] special Janus nanostrip array film as right‐side (R‐SJAF). Microscopically, Janus nanostrip with coaxial//monaxial structure effectively limits three functional substances to their own regions, avoiding adverse impact among conduction, magnetism and fluorescence to achieve enhanced fluorescence and strong anisotropic conduction. Macroscopically, SJAP realizes the division of green and red fluorescence regions, and close binding of L‐SJAF and R‐SJAF with single anisotropy enables SJAP to obtain dual anisotropic conduction. The high integration of micro and macro portion endues SJAP with dual anisotropic conduction, magnetism and red‐green two‐colored fluorescence. Two types of 3D Janus‐structural pipe were created by curling SJAP, achieving the structural evolution from 1D nanostrip to 2D SJAP then to 3D pipe. The new 3D pipes exhibit identical properties with SJAP. The novel SJAP and 3D pipe have wide prospect in electronic skin. This design theory and technology provide an idea to prepare other polyfunctional materials.

同时具有磁性和红绿色双色荧光的二维二维各向异性导电Janus纳米带阵列膜和衍生3D Janus结构管

通过静电纺丝构建了由红绿色双色荧光和磁性同步功能化的二维双各向异性导电从左到右结构的特殊Janus阵列防护薄膜（SJAP）。SJAP由两个紧密接合的薄膜组装而成。{[CoFe ₂ O ₄ /聚甲基丙烯酸甲酯（PMMA）] @ [聚苯胺（PANI）/ PMMA]} // [Tb（acac）₃ bipy / PMMA]特殊的Janus纳米带阵列膜作为左侧（L-SJAF）和{ [CoFe ₂ O ₄ / PMMA] @ [PANI / PMMA]} // [Eu（TTA）₃（TPPO）₂/ PMMA]右侧的特殊Janus纳米带阵列膜（R-SJAF）。在微观上，具有同轴//单轴结构的Janus纳米带有效地将三种功能物质限制在它们自己的区域，避免了传导，磁性和荧光之间的不利影响，从而实现了增强的荧光和强各向异性传导。从宏观上讲，SJAP实现了绿色和红色荧光区域的划分，并且L-SJAF和R-SJAF具有单一各向异性的紧密结合使SJAP可以获得双重各向异性传导。微观和宏观部分的高度融合赋予SJAP双重各向异性的传导，磁性和红绿双色荧光。通过卷曲SJAP创建了两种类型的3D Janus结构管，实现了从1D纳米带到2D SJAP再到3D管的结构演变。新的3D管道具有与SJAP相同的属性。新型的SJAP和3D管在电子皮肤中具有广阔的前景。这种设计理论和技术为制备其他多功能材料提供了一种思路。
