In the experimental process, PAN solutions were dried in an oven andprepared at weight ratios of 5%, 7%, and 10%, then added to 10 grams of dimethylformamide(DMF). To achieve the targeted (Co0,2Cu0,2Mg0,2Ni0,2Zn0,2)O structure in the nanofibers, cobaltacetate, copper acetate, magnesium acetate, nickel acetate, and zinc acetate metal salts wereadded to the solution at specific ratios. The addition ratios of the metal salts to the solutionranged between 30% and 50%.Scanning electron microscopy analysis of the nanofiber morphology revealed that differentPAN and metal salt ratios directly affected fiber thickness and structural integrity. It wasobserved that lower PAN ratios increased nanofiber thinness. The thinnest fibers were obtainedusing 5% PAN and 35% high-entropy metal oxide, demonstrating that solutions with lowviscosity produced finer and more homogeneous fibers during electrospinning. Metal salt ratioswere also found to significantly influence the surface structure and porosity of the fibers. Thechemical bonding structure of the synthesized nanofibers was examined using Fourier-transform infrared spectroscopy.In conclusion, this study highlights the critical importance of optimizing solution componentsin nanofiber production via electrospinning to enhance fiber quality and properties. AdjustingPAN concentration and metal salt ratios precisely play a key role in achieving the desired fibercharacteristics.
