    • Abstract

       

      Poly(acrylonitrile-co-methylmethacrylate) P(AN-co-MMA) was synthesized by precipitation polymerization method. Using Carica papaya (C. papaya) plant leaves extract, silver nanoparticles (AgNPs) were prepared via green synthesis. The copolymer solution in N,N dimethyl formamide was mixed with variable weight percentages of the prepared AgNPs (i.e., 1.0, 3.0, 5.0, 7.0 and 9.0 wt%). The produced copolymer composites were characterized by X-ray diffraction, scanning electron microscope (SEM), energy dispersive X-ray analysis, infrared spectra, dynamic mechanical analysis (DMA) and thermogravemetric analysis (TGA). Bacterial inhibition of the prepared copolymer nanocomposites was also evaluated for two types of bacteria (i.e., Staphylococcus aureus ATCC 12600 as Gram-positive bacteria and Escherichia coli ATCC 11775 as Gram-negative bacteria). SEM showed the fine dispersion of AgNPs in the copolymer matrix at 5 wt%. DMA indicated an increase in the storage modulus and a reduction in tan ${\delta}$ (damping) by increasing AgNPs loading up to 9 wt%. TGA illustrated that AgNPs improved the P(AN-co-MMA) thermal stability. AgNPs improved the bacterial inhibition of P(AN-co-MMA) against the two tested bacteria. Moreover, the prepared copolymer composites could be used for biomedical, pharmaceutical and industrial applications.
