Fabrication of aligned fibrous arrays by magnetic electrospinning

Fabrication of aligned fibrous arrays and multilayer grids by demonstrated by the process of magnetic electrospinning. A polymeric solution was magnetized with small amounts of magnetic nanoparticles and spinning process was carried out in a magnetic field that derives the magnetized electrospun fibers to align in a parallel fashion along the magnetic field lines. The resulting fibers formed parallel arrays and the method also allowed the construction of structures based on parallel arrays such as grids. The aligned fibers also led to isotropic properties such as unique electrical, optical, wetting, and mechanical performances and thus become able to generate periodic and ordered structures by MES. The aligned fibers have applications in the electronic and photonic devices, polymer composites, and tissue engineering as well as applications derived from soft lithography.
