In this paper, films of (PMMA-PC/In2O3-GO) nanocomposite were prepared by casting with different concentrations of (In2O3-GO) NPs (0, 1.4 %, 2.8 %, 4.2 %,and 5.6 %).Various techniques including scanning electron microscopy (SEM), optical microscopy, and Fourier transform infrared spectroscopy(FTIR ), were used to characterize the nanocomposites (PMMA-PC/In2O3-GO). Scanning electron microscopy (SEM) is used to describe the structural properties and changes in the surface morphology of nanocomposites. Optical microscopy is used to examine the homogeneity of (In2O3-GO) NPs within a blend (PMMA-PC). Using the vibrational modes assigned to free and hydrogen-bound hydroxyl and carbonyl groups, Fourier transforms infrared spectroscopy (FTIR) may be utilized to provide information on both blend composition and polymer-polymer interactions. Two different strains of pathogenic bacteria, Staphylococcus (G+ ve) and E. coli (G-ve) were used to investigate the effectiveness of(PMMA-PC/In2O3-GO). The findings showed that (PMMA-PC/In2O3-GO) had potent antibacterial activity and may be utilized to treat illnesses caused by one or both of these bacterial species.
