Effect of colletor on electrospinning to fabricate aligned nano fiber

Abstract

Nano-fiber is defined, as fiber having at least one dimension in nanometer range or less. Nano-fiber are widely used in tissue engineering for scaffold making, wound healing, implant materials, drug delivery or medicinal materials. There are various methods available to generate nano-fiber but electrospinning is one of the most widely used technique to produce nanofiber. The morphology and property of nanofiber electrospun by the Electrospinning process is affected by many factors like: solution concentration, feed rate, applied voltage, surface tension molecular weight, collector, temperature diameter of the orifice. Aligned nanofiber used in skeletal tissue regeneration, neural cell seeding in scaffold, fuel cell electrolytes, electrochemical sensing, bone and blood vessel engineering, composite metal reinforcement and many other applications. In the present study different types of collector have been used to see their effect on the alignment of the fiber. The obtained electrospun fibers are characterized under scanning electron microscope to see the morphology of the deposited fiber and the edge type provide with a better alignment compared with the other collector used in the present study.
