Electrospinning allows for facile fabrication of fibers from sub micron to micron scale in large quantities at a low production cost. Due to the high surface area to mass ratio, the fibers have been popular scaffolds for growing a wide variety of substances ranging from cells to nanoscale growths. Conventional electrospinning process creates thin sheets of fibers which are relatively two-dimensional, but by changing the collection template from a flat surface to an annulus we were able to redirect the polymer solution so the resulting fibers were deposited on top of the existing fiber, creating an interlinked three-dimensional network. The formed hybrid nanofiber were characterized by FT-IR spectroscopy, atomic force microscopy(AFM), scanning electron microscopy(SEM), and thermogravimetric analysis(TGA). |
