Controlling Fiber Repulsion in Multijet Electrospinning for Higher Throughput

A novel electrospinning set-up has been developed to successfully electrospin multiple jets with controlled fiber repulsion using a plastic filter. This set-up shows reduced fiber repulsion as compared to a multineedle set-up, along with increased throughput. The effect of processing parameters on the fiber repulsion in a multineedle set-up was also studied. It was found that fiber repulsion could be reduced by controlling emitter voltage and emitter/collector distance. Other important parameters studied included fiber distribution and throughput. It was found that the plastic filter set-up produced fibers with lower mean diameters and better uniformity. This novel plastic filter design for electrospinning provides increased electrospinning rates with better fiber uniformity.
