عنوان مقاله [English]
The behaviors of biological scaffolds from the attack of their mechanical behavior are a function of their microstructure. In this research,
an attempt is made to find the relationship between the microstructure and mechanical properties of the studied scaffolds. Therefore, electrospinning of 10% polyvinyl alcohol and 20% gum arabic solution was performed in different ratios (60-40, 30-70, 20-80, 10-90, 0-100), and the effect of gum arabic on physical properties, microstructure, and properties. The mechanical nature of the spun scaffolding was investigated. The structural properties of the solution and the association between its phases were investigated using a light microscope.
The viscosity of the solution was also investigated to investigate the effect of gum arabic on the electrospinning process. Fourier transform infrared spectroscopy of production scaffolds was performed to investigate the presence of gum arabic in the structure of electrified fibers. A tensile test was used to evaluate the mechanical properties of production scaffolds. The results showed that the presence of gum arabic causes the production of thinner fibers with higher density in the scaffolds and as a result of these changes, the modulus and strength of biological scaffolds increase.
