The aim of this mini review article, discussed the recent research in the field of polymer
nanocomposite deals with properties of polymer solution parameters such as viscosity, molecular weight,
concentration of polymeric substance in solution and surface tension of solution on morphological
properties of nanofibers produced by electrospinning technology such as nanofiber diameters and the
number and size of beads formed on the surface of the nanofiber web. All researches have proven that the
viscosity or concentration of the polymer solution, lead to increase the diameters of the nanofibers and
reduces the size and number of beads, as well as converting the fiber path jet from unstable and
unmonotonous to more stable. This behavior positively affects the formation and orientation of the fibers,
but did not lead to the enhancement of the crystalline and thermal properties of the nanofibers. Therefore,
other researchers studied adding nanoparticles such as salts to polymeric solutions to get rid of the number
and size of beads in the nanofiber web as a result of using low concentrations. These nanoparticles improve
the morphological properties as well as enhance the crystalline and thermal properties of the nanofiber
network, leading to increased engineering and medical applications such as wastewater treatment and drug
delivery.
