Abstract
AbstractThis research provides a new method for preparing nanoparticle‐coated viscose nonwoven fabrics, which has broad application prospects in the functional fiber industry. In this work amino‐terminated hyperbranched polymer (HBP)‐capped Selenium nanoparticles (Se NPs) were synthesized for coating viscose nonwoven fabric (VNF) via impregnation method to produce a controllable and uniform Se NPs coating on the viscose fiber surface. The prepared Se NPs and the treated VNF were characterized by the transmission electron microscope (TEM), x‐ray diffraction (XRD), x‐ray photoelectron spectroscopy (XPS), field emission scanning electron microcopy (FE‐SEM), and antibacterial measurement. The results indicate that the Se NPs were spherical shaped with an average size of 50 nm. FESEM, XRD, and XPS characterizations demonstrated that Se NPs can adsorbed and distributed uniformly on the fiber surface. Se NPs‐coated VNF showed above 99.9% bacterial reduction of Staphylococcus aureus and Escherichia coli while the Se element content on VNF was about 2.92 mg/g.
