PVC modification by incorporating silver nanoparticles on the surface

The aim of this work was to modify simple polyvinyl chloride plates using the spin coating technique, in order to obtain a smooth, uniform, antibacterial surface. In this purpose, AgNO3 was incorporated in the film deposited by spin coating and reduced using trisodium citrate in aqueous medium. Thus silver nanoparticles (AgNPs) were obtained on the material surface. The samples were characterized by FT-IR spectroscopy and microscopy to determine surface morphology and composition. Using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) analysis the migration of AgNPs was determined. Scanning electron microscopy was used to examine the microstructure and homogeneity of AgNPs on the surface. All samples were tested against Gram-positive and Gram-negative strains. © 2020, Politechnica University of Bucharest. All rights reserved.
