Antimicrobial agent, antimicrobial high-performance pom composite material and preparation method thereof

Abstract

The present invention discloses an antimicrobial agent, an antimicrobial high-performance POM composite material, and preparation methods thereof, wherein the preparation method of the antimicrobial agent comprises: Preparing a Tris-HCl buffer solution by mixing a tris(hydroxymethyl)aminomethane solution with a HCl solution; Adding the Tris-HCl buffer solution and dopamine hydrochloride, magnesium ions, hydroxide ions and solvent into deionized water, and performing a polymerization reaction to obtain Solution A; Placing solution A, hydrogen peroxide, solvent and deionized water into a reaction vessel, and performing an oxidation reaction to synthesize and obtain PDA@MgO2 antimicrobial agent. The catechol in polydopamine in the PDA@MgO2 antimicrobial agent in present application provides highly efficient modification sites, which can bond with multiple substances through its metal chelating effect and various chemical reactions. It has good compatibility, which also improves the dispersion performance of the antimicrobial agent in POM, thus enhancing the antimicrobial performance of POM composite material.
