Keywords: ,

We developed a new and simple approach to fabricate large amounts of anisometric particles via controlled fragmentation of electrospun composite nanofibers. Polystyrene nanoparticles were embedded as void precursors in silica fibers by electrospinning of mixed dispersions of silica and polystyrene (PS) nanoparticles resulting in silica fibers with defects after calcination. The mayority of the fibers could be broken at these defects via sonication resulting in rod-shaped fiber segments of defined length.
