The behaviors of bioscaffolds are a function of their microstructure. One of those behaviors that strongly depends on the microstructure is mechanical behavior. Thus, in this research, we tried to find the correlation between the microstructure and the mechanical properties of the studied bioscaffolds. To this purpose, mixtures of polyvinyl alcohol and gum Arabic solution are electrospun at various ratios, and the effect of the gum Arabic ratio on the physical properties of the polyvinyl alcohol solution and the microstructural and mechanical properties of the produced scaffolds is studied. The structural properties and phase continuity of the polymer solution are examined under an optical microscope. The viscosity of the solution is studied to investigate the effect of gum Arabic on the electrospinning process. FTIR is intended to look the existence of gum Arabic in the structure of polyvinyl alcohol scaffolds. The tensile test is used to study the mechanical properties of bioscaffolds. The results show that the presence of gum Arabic in a polyvinyl alcohol solution tends to produce scaffolds with smaller fiber and higher fiber density, and the results thereof tend to create scaffolds with higher modulus and strength.
