Influences of Collector Structure on Electric Field and Fiber Properties in Melt-Electrospinning

It is well known that the electric field has great influence on the diameter and properties of fibers during melt-electrospinning. This study introduces the influences of three types of collectors on the electric field distribution. An auxiliary electrode was used to enhance the electric field strength. Numerical simulation was used to understand the electric field distribution. Simulation and experimental results show that the electric field strength had an important influence on fiber properties. A more uniform electric field distribution capable of steadily controlling the jet behavior was obtained using the disc-shaped collector, thus effectively reducing the fiber diameter and improving fiber strength.
