    Evaluation of Chemical and Physical Properties of Biodegradable Nanofibrous Membranes

  • Original language description

    There is a growing interest in utilizing biomass and using biomaterials to produce fibrous structures with tailored functionalities. The present study reports on using electrospinning to produce nanofiber membranes based on homogenous polymeric blends of gum Arabic (GA) and poly vinyl alcohol (PVA). The produced interconnected membranes were crosslinked via heat and plasma treatments. Samples were analyzed for their chemical and physical performance using Fourier-transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), and load-elongation testing. FTIR spectra indicate the crosslinking of GA and PVA through esterification during the heat treatment, and through graft polymerization with methyl groups after methane plasma treatment. An increase in the modulus of elasticity from 85 MPa to 148 MPa is observed in the longitudinal direction (parallel to electrospun nanofibers) compared with the transverse direction. Moreover, well dispersed nanoparticles in the spinning solution tend to increase the elasticity from 41 MPa to 148 MPa while the agglomeration of these nanoparticles causes a decrease to the mechanical properties of the nanofibers. The produced biodegradable electrospun membranes have multiple potential applications in many fields, especially for medical and antibacterial uses.
