Gelatin is a natural polymer with strong polarity. It has molecular chains connected through strong hydrogen bonds, constituting a 3D macromolecular network. Because of its many merits, such as its biological origin, biodegradability, biocompatibility and commercial availability at relatively low cost, gelatin has been widely used in the pharmaceutical and medical fields. Electrospinning is a simple and versatile technique to generate nano to micrometer fibrous structures which are very similar to the natural febrile extracellular matrix (ECM). Morphology of electrospun fibers depends on solution, device and environmental parameters. Then in this research, we electrospinning 9 samples in different device conditions 3 different voltage (10,12,15 kV) and 3 different distance (distance between nozzle to collector:TCD) (10,15,20 CM). we surveyed FIBERS CHARACTERISTICS in device electrospinning parameter by SEM and FTIR tests that they observed nanofibers in the average standard deviation of them were 10-15% and their range varies also were between 79 to 139. and I also understood by increasing the voltage as well as the TCD, more fibers can be obtained with less beads and more uniformity Manuscript profile

Electrospinning has been recognized as an efficient and simple technique for the fabrication of polymer nanofibers for biofunctionals. Recently, various polymers have successfully been electrospun into ultrafine fibers. Electrospinning is an extremely promising method for the preparation of tissue engineering scaffolds. In this study, nanofibers gelatin was electrospun at 20% v/v optimized content. To produce gelatin nanofibers optimally, production parameters need to be investigated. In the electrospinning, device (voltage and distance) parameters were determined to be effective; as a result, these parameters were researched and the influences of electrospinning device parameters (voltage & distance) on properties of gelatin nanofibers were evaluated. These parameters affected the diameter size, uniformity, hydrophilicity and thermal degradation of electrospun gelatin nanofibers. All of these properties were examined by SEM, FTIR, CA, BET, XRAY and TGA tests and finally optimum gelatin nanofibers can be used in many applications including cell culture, drug delivery and tissue engineering.
