The invention discloses a nano antibacterial material and a preparation method and application thereof. The fusiform
zinc oxide nanorod antibacterial material is prepared by taking
zinc acetate as a
zinc source,
ammonia water as an
oxygen source, clay as a dispersing agent and
rosin as a dispersing agent and a capping agent through a hydrothermal method. The two ends of the fusiform
zinc oxide nanorod are needle-point-shaped,
rosin is adsorbed on the surface of the fusiform
zinc oxide nanorod, and the antibacterial performance of the fusiform
zinc oxide nanorod is greatly improved. The preparation method is simple, mild in condition and high in
repeatability, and overcomes the defects of the existing nano material preparation. The obtained zinc
oxide nanorod can be used as a bacteriostatic material in the fields of
tissue engineering, food, textiles, coatings and the like.
