NOVELTY - Preparing hydrophobic biomedical antibacterial agent comprises (i) mixing 1-3 pts. wt. silicone monomer with 10 pts. wt. solvent, and stirring the mixture uniformly to obtain silicone monomer solution, (ii) mixing 5 pts. wt. graphene quantum dot coated nano silver antibacterial agent with 10 pts. wt. solvent, and stirring the mixture uniformly to obtain graphene quantum dot coated nano silver antibacterial agent dispersion, (iii) mixing prepared organosilicon monomer solution with graphene quantum dot coated nano silver antibacterial agent dispersion, and stirring the mixture uniformly to obtain hydrophobic silane graphene quantum dot coated nano silver antibacterial agent dispersion, and (iv) cooling the hydrophobic silane graphene quantum dot coated nano silver antibacterial agent dispersion at room temperature and drying to obtain final product. USE - The method is useful for preparing hydrophobic biomedical antibacterial agent.
