- Abstract
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.
