In this work, the ethylcellulose/gelatin blends at various weight ratios in water/ethanol/acetic acid solution were electrospun to fabricate nanofibers with tunable physical properties. The compatibility was predicted based on Hansen solubility parameters and evaluated by rheological measurements. properties characterized scanning electron microscopy, porosity, differential calorimetry, thermogravimetry, Fourier transform infrared spectroscopy, water contact angle. Results showed that entangled structures among ethylcellulose gelatin chains through hydrogen bonds gave rise a fine morphology of composite fibers improved thermal stability. higher ratio (75%), possessed hydrophilic surface (water angle 53.5°), adequate uptake ability (1234.14%), while proportion (75%) tended be highly stable hydrophobic 129.7°). This work suggested have potentials as materials for bioactive encapsulation, food packaging, filtration applications.
