Abstract Content

Electrospinning is a fiber forming technique that has recently experienced a dramatic increase in interest and activity. The production of fibers though this approach allows the control of polymer structure and morphology with fiber diameters as small as 50 nanometers. The chemical and mechanical properties of these nanofibers are often critical to the macroscopic performance of the fiber mat in applications as diverse as filtration and cell growth. There is a limited range over which mechanical properties can be varied for a given polymer fiber. However if a heterogeneous fiber structure can be created, then the possibilities for changing both chemical and mechanical properties becomes much broader. One approach to this involves creating a radially heterogeneous fiber structure through co-axial and triaxial electrospinning. Such an approach has been developed using concentric needles in a conventional electrospinning arrangement. Results for both co-axial and triaxial fibers will be discussed.
