Abstract

The paper deals with the design of a new effective electrode for coaxial electrospinnig process. This concept is based on a circular symmetric design enabling formation of a double polymeric layer. The layer is created by overflowing of one solution over the other. Subsequently, the double layer is exposed to critical voltage in the DC electrospinning process to create core/ shell nanofibers. The electrode geometry has been designed using the FEM analysis of the electrical field. As a result, appropriate distribution of the electric field on the electrode surface has been found. The manufactured electrodes have been verified experimentally. The results of both the analysis and experiment have proved, the design meets requirements for an appropriate location of Taylors cones on the polymeric surface and thus increases potential for production of coaxial nanofibers.
