Patterned deposition of nanofibers

The technology of patterned deposition of nanofibers in electrospinning can greatly improve the utilization of material,decrease procedures and lower cost.Three grounded metallic plates with different holes of circle,rectangle and triangle shapes respectively were utilized as collectors.Experiment results show that,to such three different shapes of holes,the deposition density of nanofibers at the vertex of holes and around the holes is much higher than that on the hole except the vertex.The reason is that the positively charged as-spun nanofibers around the hole in the collector are manipulated by the asymmetry electrical field near the hole to pattern deposition.This technique will offer experiment background for patterned deposition in mass fabrication of nanofibers in the future.
