摘要：

A study was conducted to demonstrate the preparation of silver nanoparticles (NP) embedded into ion-exchange resin (Ag-IER) by the polyol method. The silver NPs were characterized by several instrumental analyses, such as field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) and energy-dispersive X-ray emission (EDX). Their anti-bacterial activity was tested using Escherichia coli, as it was known as an indicator bacteria. Their antibacterial effect was also investigated at a low silver loading level and silver ion release conditions. Silver NPs were embedded onto bead type porous IER that had sulfonate groups to prepare the antibacterial materials. It was also observed that the color of the IER beads changed from dark muddy yellow to black after the embedding of the silver NPs.
