Effect of Composite Spinneret Systems on the Formation of Helical Nanofibers via Electrospinning

摘要

In this work, we report an approach to prepare helical nanofibers via co-electrospinning. The results of the experiment demonstrate that Composite spinneret is necessary for the formation of helical fibers. The off-centered system could produce more uniform helical structures. In order to explore the effect of contact time of the core-shell solutions to form helical nanofibers, three kinds of spinnerets with different structures are compared. The contact time influence the degree of compatibility of the components. Suitable compatibility is conducive to the formation of helical nanofibers.
