Abstract. Polyaniline (PANI) semiconductor polymer and cadmium sulfide nanoparticles
(CdS NPs) was prepared by chemical oxidation method and sol-gel method respectively. (10-
40) wt% content of CdS NPs was added polyaniline conductive polymer powder to prepared
PANI-CdS nanocomposites. The Fourier transform infrared analysis FT-IR spectra of the
prepared samples revealed that the effective groups and peak locations referred to the
confirming chemical bond are well-matched with the reported literature. The XRD results
shows a very wide peak of PANi polymer which indicate to some crystallinity of PANi
structure. Whereas the diffraction pattern of CdS NPs shows high crystallinity and
polycrystalline nature of hexagonal wurtzite phase. The diffraction pattern of PANI-CdS
nanocomposites shows lower peaks intensity than of CdS NPs and improved with the increase
of CdS NPs content. The antibacterial activity of PANi and PANi-CdS nanocomposites was
estimated by agar well diffusion method against four types of pathogenic bacteria Proteus
mirabilis, Staphylococcus aureus, Escherichia coli and Klebsiella pneumonia. It was found that
there is a strong antibacterial activity and the greatest effect was for the prepared PANi-CdS
NPs 40 wt% and the highest activity was found against Staph. aureus bacteria as well as with
the increase of nanoparticles content
