PARTICULATE ANTIMICROBIAL HYBRID SYSTEM

The invention relates to a hybrid material, in particular provided as an additive relating to materials, substances and/or coating materials for producing an antimicrobial, antiviral and/or fungicidal effect, and which comprises particles, each of which comprising at least one carrier material being at least partially coated with at least two different metals, wherein at least one first metal and one second metal are, at least with their respective surfaces, in electrically conductive contact to each other. According to the invention the first metal comprises at least one semiconductive compound of at least one transition metal element, which exhibits multiple oxidation states and allows a change of the oxidation states by means of catalytically active centers, and the second metal comprises at least one electrically conductive silver semiconductor, wherein both metals establish half cells which are short-circuited in the presence of water and oxygen and thus develop an antimicrobial, antiviral and/or fungicidal effect, wherein the carrier material comprises at least one material being adapted to the substance and/or the coating material and their use. The hybrid material according to the invention can be advantageously used as antimicrobial additive for various materials, substances and/or coating materials, preferably lacquers, paints, plastering, polymers and/or cellulose.
