Functionalization of silk fabric using hyperbranched polymer coated attapulgite nanoparticles for prospective UV-resistance and antibacterial applications

Abstract

Herein, the Attapulgite nanoparticles (ATP NPs) coated silk fabric was prepared by impregnation method using hyperbranched polymer as addition agent. The ATP NPs and prepared silk fabrics were characterized by means of scanning electron microscope (SEM), ultraviolet-visible (UV-Vis) spectroscopy, Fourier transform infrared spectrophotometer (FTIR), X-ray diffraction (XRD), Energy Dispersive Spectrometer (EDS). The results of SEM, EDS, FTIR and XRD confirmed that ATP NPs were successfully coated on the surface of silk fabric. Not only did the treated silk fabrics possess excellent antibacterial property and antibacterial resistance, but also exhibited outstanding anti-ultraviolet performance, which can meet the requirements of multifunctional products.
