Abstract: Provided is an antimicrobial coating material comprising one or more biocides encapsulated in inorganic-organic shells. The antimicrobial coating material can be applied on porous materials or porous media to form and antimicrobial coating without changing the physical properties and the functions of porous materials or porous media. The coating provides a durable, multi-level antimicrobial performance at high temperature through contact-killing, release-killing, anti-adhesion and self-cleaning. Also provided is a method of producing the antimicrobial coating material.

Abstract: The antimicrobial coating material for surface coating is formed from encapsulated biocides. The biocides include at least one antimicrobial component. The biocides are encapsulated in inorganic-organic shells which are permeable to the biocides. The organic materials may include at least one nonionic polymer. The inorganic-organic shells encapsulate and contain the biocides to form capsule structures for storage and release of the biocides. The capsule structures may be single capsules or capsule-in-capsule structures. The inorganic materials may be present in a concentration of 0.5-95 wt % of the inorganic-organic shells. Alternatively, the inorganic materials may be present in a concentration of 5-60 wt %. The inorganic materials and the organic materials are each intermixed, with respect to one another, in structures of the inorganic-organic shells. These structures may be an attachment structure, a hybrid structure or a multi-layered structure.
