Morphology and mechanical properties of PAN nanofiber mat

Abstract

Abstract Nanofibers have acquired greater interest due to their vast variety of possible uses. Nanofibers offer several options to change things physically and chemically during or after the manufacturing process to give them new properties. To exploit the full potential of nanofibers, it is necessary to comprehend the link between the mechanical characteristics, particularly tensile strength, of a nanofiber mat and its morphology. Electrospinning is a rapidly developing polymer processing technology because it provides a simple and effective method for manufacturing nano continuous fibres. This method permits the deposition of nanofibers on revolving collectors. Rotating collectors, such as the drum and electrodes with a gap between them, may readily form oriented fibres. Polyacrylonitrile is a common precursor material for carbon nanofibers (PAN). This research investigates the impact of collector drum’s rotation speed on the morphology of the nanofiber mat and discusses the mechanical properties of Polyacrylonitrile (PAN) electro spun nanofiber mats with precisely aligned nanofibers. PAN nanofiber mats have more tensile strength (~37 %) than PA6 nanofiber mats and have (50 %) less elongation than PA6 nanofiber mats, according to a comparison with previous studies.
