Abstract

This study investigates the impact of varying concentrations of zinc acetate dihydrate on the morphological and surface properties of electrospun polyvinyl alcohol (PVA) fiber layers applied to magnesium substrates, intended for use as a biodegradable implant material. Electrospinning was employed to fabricate PVA/ZnAc composite fiber layers by incorporating different ZnAc concentrations into PVA solutions. The researcher focuses on evaluating key parameters of the resulting fiber layers, including fiber diameter, layer thickness, porosity, and surface wettability, as determined by contact angle measurements. The experimental results demonstrate that increasing the concentration of zinc acetate dihydrate leads to a noticeable enlargement in fiber diameter and a corresponding increase in both the overall thickness and porosity of the electrospun layers. Specifically, the fiber layer at 50% ZnAc concentration exhibited the highest thickness of 0.0108 mm, while also producing the largest average fiber diameter of 2.162 nm ± 0.86 nm. Additionally, higher ZnAc concentrations were found to enhance the hydrophobic nature of the coatings, as indicated by higher contact angle values. Among all samples, the 20% ZnAc concentration demonstrated superhydrophilic behavior with the lowest contact angle value of 44.76° ± 1.84°. However, this increase in hydrophobicity is also associated with an undesirable rise in the corrosion rate of the magnesium substrate, suggesting a trade-off between surface modification and material stability. These findings highlight the importance of optimizing ZnAc content in PVA solutions to achieve a balance between desired fiber morphology and corrosion resistance. Ultimately, the study underscores that careful selection of zinc acetate dihydrate concentration is vital for developing functional and reliable electrospun PVA/ZnAc coatings for magnesium-based biodegradable implants.
