Optimization of Electrospinning Parameters for Poly (Vinyl Alcohol) and Glycine Electrospun Nanofibers

EasyChair Preprint 5102

Abstract

The nanofibrous scaffold that mimics the extracellular matrix in structure has gained immense popularity, especially in the tissue engineering field, in the last decade. Several techniques have been utilized for fabricating nanofibrous scaffolds. Electrospinning is one of the most popular techniques to generate the nanofibrous scaffold, owing to processability, a wide variety of polymers and materials used, and affordability. This research aims to fabricate a smooth and uniform nonfibrous structure from poly (vinyl alcohol) and glycine aqueous solution. The effect of aqueous solution concentration and PVA to Gly different ratios on electrospinnability was investigated qualitatively utilizing scanning electron microscopy. Three different concentrations have been investigated 6 (w/v) %, 8 (w/v) %, and 10 (w/v) %, each one of these concentrations have been electrospun in different PVA to Gly weight ratios 4:1, 4:2, 4:3, and 4:4. The nanofibrous structure was attained with 8 (w/v) % and 10 (w/v) % with average fiber diameter in the range of 232±66 nm to 591±186 nm. Therefore, the morphology of nanofibers was attributed to the effect of solution concentration, as well as was attributed to the electrospinning parameters including needle-to-collector distance, feeding rate, and applied voltage.
