摘要

In this study, effective surface functionalization and polymerization were investigated based on 2-chloro-3',4'-dihydroxyacetophenone (CCDP) grafted poly[(2-hydroxyethyl methacrylate)-co-(2-(dimethylamino)ethyl methacrylate)] [poly(HEMA-co-DMAEAM)-g-CCDR CGPH]. The surface polymerization was carried out via radical polymerization of N-isopropyl acrylamide (NIPAAm) and ring opening polymerization (ROP) of carprolactone by utilizing a hydroxyl functional group of HEMA on a surface coated substrate. The antibacterial characteristics were confirmed by the inhibition zone using dopamine conjugated CGPH substrate with AgNO_3. The silver nanoparticle immobilized by dopamine shows a significant antimicrobial effect against both Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli under normal and extreme stress conditions. The immobilized surface was confirmed through X-ray photoelectron spectroscopy (XPS) and Field Emission scanning electron microscopy (FE-SEM).
