Use of coaxial gas jackets to stabilize Taylor cones of volatile solutions and to induce particle-to-fiber transitions
A novel method to control the stability of Taylor cones during electrospinning/electrospray of solutions with highly volatile solvents is presented. An additional advantage is that fiber-to-particle transitions are also controlled without changing the chemistry or the voltage/current characteristics. The Figure shows the transition from particles to fibers effected by simply changing the gas flow rate through an outer capillary.
