Traditional electrospinning techniques for converting mammalian gelatin into nanofibers are hampered by the inherent property of gelatin to gel at room temperature. To inhibit gelation of gelatin, it has been proposed to use solvents such as formic or acetic acid. This study suggests a novel approach, employing gamma-valerolactone (GVL) as a green solvent to facilitate room temperature electrospinning of gelatin into nanofibers. We initially examined the viscoelastic properties by modulating the GVL and gelatin concentrations, discovering that a particular GVL concentration can inhibit room temperature gelation. This finding enabled us to determine the optimal GVL volume for easy synthesis of gelatin nanofibers at room temperature, successfully preparing gelatin nanofibers with an average diameter of 194.39 nm through electrospinning. Nanofibers created with safer solvents such as GVL hold considerable promise for utilization in fields including food packaging and oil-water separation.
