【 摘 要 】

Magnetic field assisted electrospinning is supplemented by conductive sheets that envelop the magnets and havethe same potential as the deposition electrode. By optimizing the experimental conditions, it is possible to produce wiresmade of polymer nanofibers that incorporate longitudinally oriented magnetic particles. The morphological and magneticcharacterizations confirm the preferential orientations. The new nanofiber wires are easily aligned along the maximum intensityline of the applied magnetic field. Moreover, the nanostructured wires have high longitudinal elastomagnetic strainand high transversal deflection as a response to magnetic field stimuli. Therefore, these new threadlike aggregates of magneticnanofibers could be very appealing for application in all microelectronic or biomedical devices whose functionality requiresorientation or deformation.
