Claim Text:
1. A polymeric material with antimicrobial and/or biocidal properties for making plastic products with antimicrobial, antifouling, and biocidal properties, wherein the polymeric material comprises a thermoplastic and/or thermostable resin and/or organic coating of painting type comprising nanoparticles from 4 to 500 nanometers, of an element or inorganic compound with antimicrobial and biocidal properties, wherein the nanoparticles of the element or inorganic compound with antimicrobial properties are pre-treated to improve final dispersion and are completely embedded in the thermoplastic resin and do not protrude from the surface of the resin, and wherein the nanoparticles of the element or inorganic compound with antimicrobial properties form agglomerates of sizes from 0.1 to 100 micrometers, wherein the ratio in weight between nanoparticles of the element or inorganic compound and the thermoplastic and/or thermostable resin and/or organic coating of painting type is between 1 and 80% in weight, and wherein said agglomerates are homogeneously dispersed in the resin, in order to obtain an agglomerate density greater than 2, wherein said agglomerate density is defined as 100 times the ratio between the average number of agglomerates and the average volume of agglomerates, observed in a determined volume, divided by the ratio in weight of nanoparticles of the element or inorganic compound and the thermoplastic and/or thermostable resin and/or organic coating of painting type.
