چکیده
Gelatin is a natural polymer with strong polarity. It has molecular chains connected through strong hydrogen bonds, constituting a ۳D 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 ۹ samples in different device conditions ۳ different voltage (۱۰,۱۲,۱۵ kV) and ۳ different distance (distance between nozzle to collector:TCD) (۱۰,۱۵,۲۰ 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 ۱۰-۱۵% and their range varies also were between ۷۹ to ۱۳۹. and I also understood by increasing the voltage as well as the TCD, more fibers can be obtained with less beads and more uniformityکلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
