Abstract

original image

A facile approach to align Ag nanowires (AgNWs) on a macroscopic scale via a magnetic-field-assisted electrospinning technique is developed by S.-H. Yu and co-workers. The AgNWs assembled within the polymer fibers are arranged in parallel and can be further aligned by controlling the arrangement of the fibers into hierarchical structures, as described on page 2936. This method may provide a general way to assemble other nanowires within polymer nanofibers with controllable density on a macroscopic scale, especially for the combination of inorganic nanowires as fillers or functional components with flexible polymers.
