Abstract

In this work, the silk fibroin/cellulose blend nanofibrous membranes modified with sodium-3-sulfobenzoate (S-SCBNM) were fabricated by electrospinning technique for lysozyme adsorption. The morphology and structure of membranes was observed. The effect of sulfate contents, pH values and concentration of lysozyme on adsorption performance were studied, respectively. The reuse capacity was evaluated. The results showed that the resultant S-SCBNM exhibited integrated properties of ultrathin fiber diameter (148 nm), fast adsorption equilibrium, excellent adsorption performance (636 mg g⁻¹) and good reversibility. We envision that this new class of green and natural blend membranes is particularly promising for the development of proteins separation.
