NOVELTY - A stable and efficient antibacterial composition comprises 2-3 wt.% two-dimensional material, 0-0.5 wt.% organic dispersant and remaining solvent oil. USE - The antibacterial composition is used in antibacterial materials. ADVANTAGE - The antibacterial composition is stable and highly efficient, solves the problem of easy agglomeration of graphene and exhibits stronger surface effect which improves the adsorption capacity of the antibacterial composition to microorganisms, exhibits excellent compatibility between the inorganic phase and the organic phase in the system and maintains a uniformly dispersed storage state at high and low temperature cycle, ensures high antibacterial properties, stability and wear resistance. The preparation method is simple and convenient, exhibits strong repeatability which is conducive to mass production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the stable and efficient antibacterial composition comprising mixing the two-dimensional material and metal hydrate at > 200℃ and mixing with the solvent oil and organic dispersant to obtain the product.
