Disclosed is a method for preparing an attapulgite-based pH-responsive antibacterial material, including: directly spraying a natural aldehyde-based antibacterial agent onto an attapulgite powder under stirring, and constantly stirring the attapulgite powder for 20-30 min; grinding the attapulgite powder in a ball mill for 30-60 min to obtain a ground attapulgite powder; placing the ground attapulgite powder in a stirred tank, and spraying a chitosan-citric acid aqueous solution onto the ground attapulgite powder; after spraying, constantly stirring the ground attapulgite powder for 30-120 min; and finally drying the ground attapulgite powder to obtain a dried attapulgite powder, sieving the dried attapulgite powder to obtain a sieved attapulgite powder, and packaging the sieved attapulgite powder to obtain the antibacterial material.

Disclosed is a method for synthesizing an antimicrobial base. The method comprises treating a Silver salt in a reaction mixture. The method further comprises adding one or more reactants to the reaction mixture in a pre-defined ratio. Further, the method comprises heating the reaction mixture at a first temperature between 45° C. to 90° C. for a first period of 5 to 8 hours. Furthermore, the method comprises stabilizing the conversion by adding a ligand and a stabilizing agent. Subsequently, the method comprises digesting the reaction mixture at a second temperature between 45° C. to 65° C. for a period of 2 to 4 hours to form an end product. Finally, the method comprises filtering the reaction mixture. The sub-micron particle forms a dispersion containing the colloidal silver particles (Ag.sup.0), thereby forming the antimicrobial base.
