Abstract
TiO2 nanomaterials are widely used in the antimicrobial field, but their use conditions are limited because of their large bandgap width. By improving the morphology and structure of TiO2 nanomaterials and composite with other substances, this shortcoming can be effectively improved. In this paper, the morphology and structure of TiO2 nanocomposite antibacterial materials are introduced first. Optimizing the TiO2 nanostructure can maximize its photocatalytic activity and improve antibacterial efficiency. Secondly, the types and application scope of TiO2 nanocomposites are introduced, the current research status of TiO2 nanocomposites is described, the latest research results of TiO2 nanocomposite antibacterial materials and the possible challenges and limitations of TiO2 nanocomposite antibacterial materials in practical applications are understood. Then, the widely used antibacterial material standards are described, and the commonly used antibacterial detection methods are summarized from the standards. Finally, the summary and prospect are made. It is of great social significance and economic value to develop inexpensive, efficient, safe, and non-toxic TiO2 nano-antibacterial materials in the future.
