The effects of various melt-electrospinning parameters on the morphology and fiber diameter of polypropylene of different tacticities were studied. The objective was to evaluate the influence of electric field strength at various melt flow indexes of polypropylene on fiber uniformity, morphology, and diameter. A comprehensive methodology was applied, measuring the morphology and diameter of collected fibers under varying parameters. Results demonstrated that molecular weight was the predominant factor in determining the fiber diameter, with atactic polymers having molecular chains incapable of crystallization tending to produce larger diameter fibers than isotactic polymers capable of crystallization, even at lower molecular weights. Additionally, the polymer volume supplied to the electric field at a given time was found to affect fiber diameter, with systems supplying the smallest volume resulting in the smallest fiber diameter. These observations contribute valuable insights into the processing of polypropylene fibers through melt-electrospinning techniques.
