The application and development of natural antibacterial (ANB) nanocomposites (NCs) films have always been the concern of biomedical studies. In the current study, three different amounts of antimony trioxide nanoparticles (Sb2O3NPs) were incorporated with (60:40)wt.% of polyvinyl alcohol (PVA) and poly(N-vinyl pyrrolidone) (PVP) polymer matrix (PM) via casting method. The samples were labeled as N1, N2, and N3 depending on the PM to Sb2O3NPs ratio. The NCs films were investigated by light microscope (LM), Fourier transformation infrared (FTIR) and UV/visible spectrum. The NPs were perfectly diffused on the homogeneous surface of PM without aggregations. The sharpness of FTIR peaks increased with the increasing of Sb2O3NPs. The UV/visible properties were measured with wavelength between 190 to 1100 nm. The optical coefficients improved after loading except the transmittance (T%) and indirect energy gap (Eg). The nanocomposite (NC) films absorbed about 97% from the UV ray in the =220 nm. The absorption edges decreased with the increase of energy from 4.0 eV to 3.85 eV. The indirect Eg values decreased from 4.0 eV to 3.8 eV. Each type of gram negative pathogenic bacteria was affected by the addition of Sb2O3NPs. The inhibition zones were increased with the increasing of NPs contents from (0-9.5) mm for E-coli and from (0-14.4) mm for Proteus
