The invention belongs to the technical field of biopolymer materials and provides a multifunctional polymer coating containing a mesoporous silica nano micro container and a preparation method thereof.The coating comprises mesoporous silica nanoparticles where a self-healing reagent/antibacterial agent is supported and a polymer material with the self-healing/biosorption-resistant function.The mesoporous silica nanoparticles are embedded in the polymer material.The embedding method includes the steps that a silane coupling agent is grafted to the mesoporous silica nanoparticles to form an out-of-particle double-bond structure, then the mesoporous silica nanoparticles are subjected to self-healing reagent/antibacterial agent supporting, and the modified and supported mesoporous silica nanoparticles are embedded in the polymer material with the self-healing/biosorption-resistant function through the covalent bond action.According to the coating, the self-healing material/biosorption-resistant material is combin
