Herein, discarded eggshell membrane (ESM) hydrogels were prepared with polyvinyl alcohol (PVA) using aqueous media under electron beam irradiation (EBI). The interwoven and coalescing fibrous networks in the ESM and the presence of some functional groups such as carboxyl, hydroxyl, amino, phosphoryl, and thiol facilitate the formation of three-dimensional (3D) hydrogel of ESM/PVA. Various characterization techniques such as scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and X-ray diffraction (XRD) were performed to examine the physical and of the as-synthesized hydrogels. Also, the swelling kinetics of the hydrogel was studied in water. Overall, the strategy presented in this work shows a cost--effective and eco-friendly approach for preparing ESM-based hydrogel. It is expected that the as-prepared ESM/PVA hydrogels can be applied in the biomedical field, such as wound dressing applications. |
