Electrospinning technology has been recognized as a considerable method to fabricate submicron fibers. Especially, the electrospinning have been developed with the combination of complicated fluid devices to engineer multi-functional fibers. Herein, we study the novel multi-compounds electrospinning consisting of high conductive aqueous solutions for the inner fluid and low conductive polymeric solution for the outer fluids. Interestingly, the driving fluid among inner fluids at the equivalent conductivity is switched at a frequency. The switching of Taylor cone results in the alternative embedding of inner components which are proportional to the number of capillary. This result demonstrates that one high conductive fluid can be the driving fluid, but it can be alternative among the inner fluids. The alternative embedding of multi-components in nanofibers might be applied into tissue engineering, biomaterials, or drug delivery carriers. |
