Research Progress on Preparation Methods of TiO₂ Antibacterial Coating

TiO₂ antibacterial coating has the characteristics of long sterilization time and minimal pollution damage, and has an unparalleled application prospect compared with traditional fungicides. The bactericidal mechanism and coating types of TiO₂ coatings are reviewed, and the advantages, disadvantages and application status of main preparation processes, such as sol-gel method, electro-deposition method, magnetron sputtering method, plasma spraying method, and micro arc oxidation method are introduced. The future research direction of TiO₂ antibacterial coating is prospected.
