Influence of Adding Silver Nanoparticles on Structural and Optical Characteristics of PMMA Nanopowders for Antibacterial Applications

Abstract

The study aimed to prepare a combination of polymethyl methacrylate/silver nanoparticles as an antimicrobial product. We achieved the formation of pure PMMA and PMMA/AgNPs samples using clove plants as a colloidal extract. The possible functional groups and surface morphology were examined. The surface plasmon resonance (SPR) was reported by the UV-visible absorption spectra. The antibacterial performance of the prepared samples was studied against Gram negative and Gram positive bacterial strains. The same functional groups were revealed with slight shifting to lower wavenumbers for PMMA/Ag sample. SEM analysis established that the preparation of PMMA by the extraction approach led to the creation of nano-to-micro-sized structures with significant grain aggregation when AgNPs were added. Finally, the antibacterial analysis presented an obvious influence by adding AgNPs to pure PMMA powder.
