Using the polymer complexing agent with no toxic and side effects as the carrier, the Silver 1 Iodide nanomaterial is synthesized in situ on the polymer complexing agent by the in-situ synthesis technology to obtain the silver iodide complex dispersion. And excellent biocompatibility, the silver iodide obtained by the technical solution of the present invention and the polymer complexing agent have a synergistic effect, do not cause any irritation to the skin, mucous membranes, eyes, etc., and overcome the shortcomings of the existing silver-based antibacterial agents. It also has strong antibacterial effect and excellent dispersing performance. It can be added to other materials to increase the antibacterial performance of the material, and can also be directly used for surface disinfection and sterilization of skin, medical equipment and household items.
Prepare iodine salt aqueous solution and silver salt aqueous solution with molar concentration of 0.01~1.0mol/L, under the condition of stirring and temperature of 20~90 ℃, and control the flow rate, inject the above-mentioned substances into the polymer complexing agent aqueous solution, in the After the in-situ Silver 1 Iodide is generated in the polymer complexing agent, ultrasonic treatment is performed for 30-60 min under the reaction temperature condition to obtain the silver iodide complex dispersion. The invention utilizes the polymerization inhibition effect of the polymer complexing agent to generate nano silver iodide in-situ in the polymer complexing agent, and the prepared nano Silver 1 Iodide has small particle size, narrow distribution, and is easy to stably disperse in water. The silver iodide complex antibacterial agent provided by the invention has a sterilization rate of up to 99.9%, and can be added to other materials to increase the antibacterial properties of the materials, and can also be used for surface disinfection and sterilization of skin, medical instruments, household items and the like.
