AgxZn1−lic ">xO1−0.5x and Ag0.02Z0.98O0.99/polyaniline (AZO/PANI) nanocomposites were prepared by citrate sol–gel method and in situ inverse microemulsion method, respectively. The composition, structure and morphology of the samples were characterized by means of modern testing techniques. The antibacterial activities of the as-prepared samples against Staphylococcus aureus, Escherichia coli and Candida albicans were carried out using inhibition zone, minimum inhibitory concentration and minimal bactericidal concentrations methods under the irradiation of sunlight. Results showed that the antibacterial activity of AgxZn1−lic ">xO1−0.5x was better than that of ZnO, and it was optimum when the mole ratio of Ag was 0.02. The AZO/PANI composites had preferable antibacterial effect than AZO, and shown the strongest antibacterial activity when the mass fraction of AZO was up to 60 %.
