Document Type and Number:
WIPO Patent Application WO/2024/060307
Kind Code:
A1
Abstract:
A preparation method for an antibacterial nanocomposite material and the use thereof. The antibacterial nanocomposite material is prepared by using porous tourmaline as a carrier, loading a guanidyl-containing organic polymer antibacterial agent thereon to obtain a functional hybrid material, crushing same, and then sealing the surface of the functional hybrid material with benzotriazole and a metal salt solution. According to the technical solution, an antibacterial nanocomposite material, which has a transparent color, a lasting and stable antibacterial effect and a uniform size, is prepared by means of a simple preparation method. The material has an antibacterial rate of larger than 99% for Escherichia coli, an antibacterial rate of larger than 99% for Staphylococcus aureus, and an antibacterial rate of larger than 90% for Candida albicans. The material is suitable for the technical field of functional nanomaterials; and the material can be used as an antibacterial material in coatings, textiles, protective articles, medical materials, plastic vessels, digital products and household electrical appliances.
