Synthesis and Morphology Characteristics of PMMA/CeO2 /SiO2 Nanostructures for Antibacterial Application

Abstract

In this work, nanocomposite films are prepared by casting method from polyme-thyl methacrylate (PMMA) with various ratios of nanomaterials (SiO2–CeO2): 1.4, 2.8, 4.2 and 5.6 wt.%. The structural properties are investigated by means of the optical and field emission scanning electron microscopies. The results show that there is a good-homogeneity distribution of SiO2/CeO2 nanoparticles within the polymeric mixture. The PMMA/SiO2/CeO2 nanocomposites are test-ed for antibacterial application. The results show that the inhibition-zone diam-eter increases with increase in the SiO2/CeO2 nanoparticles’ concentrations.
