Composite Based on Hollow Glass Microspheres Modified With Silver Nanoparticles

This paper analyzes composite materials based on K 25 hollow glass microspheres modified with silver nanoparticles (Ag NPs). The nanoparticles were produced by an eco-friendly green method using an aqueous plant extract from Taraxacum root as a reducing agent. The synthesis of the nanoparticles and their deposition on the surface and within the pores of the microspheres were achieved simultaneously through ultrasonic treatment, followed by thermal processing at 300 – 350°C. The developed composites, consisting of K 25 hollow glass microspheres with supported silver nanoparticles, were characterized using scanning electron microscopy (SEM), infrared (IR) spectroscopy, and x-ray diffraction (XRD). The elemental composition was determined by energy-dispersive x-ray spectroscopy (EDS). The results demonstrate the effectiveness of the proposed method for depositing silver nanoparticles onto the surface of glass microspheres.
