Structures, Morphological Control, and Antibacterial Performance of AgTiO2 Micro-Nanocomposite Materials

Abstract EN

Structures, morphological control, and antibacterial activity of silver-titanium dioxide (Ag/TiO2) micro-nanocomposite materials against Staphylococcus aureus are investigated in this study.

Horizontal vapor phase growth (HVPG) technique was used to synthesize the Ag/TiO2 micro-nanomaterials, with parameters of growth temperature and baking time.

The materials were characterized by using scanning electron microscopy (SEM), energy dispersive X-ray (EDX) spectroscopy, and atomic force microscope (AFM).

The result indicated that the HVPG technique is able to synthesize Ag/TiO2 with many shapes in micro- and nanoscale such as nanoparticles, nanorods, triangular nanomaterials, and nanotubes.

The results showed that the shape of micro- and nanocomposites material could be arranged by adjusting the parameters.

The results revealed that the nanorods structure were obtained at 1000°C growth temperature and that 8 hours of baking time was ideal for antibacterial application.

Treating the S.

aureus stock with Ag/TiO2 nanocomposites is able to reduce bacterial growth with a significant result.
