Abstract | Provided are: cerium oxide nanoparticles that have excellent antimicrobial and antiviral activity and have low coloration; and a resin composition and a fiber material that include the cerium oxide nanoparticles. The cerium oxide nanoparticles include, as a stabilizer, a basic amino acid, an alicyclic amine, an aromatic heterocyclic compound that includes a nitrogen atom in the ring structure thereof, a polymer that has a heterocyclic amine skeleton, or a boron compound, and are characterized in that the APHA of a 1% by mass dispersion of the particles is no more than 400. The resin composition and the fiber material include said nanoparticles and have low coloration.
L'invention concerne : des nanoparticules d'oxyde de cérium qui ont une excellente activité antimicrobienne et antivirale et une faible coloration ; et une composition de résine et un matériau fibreux qui comprennent les nanoparticules d'oxyde de cérium. Les nanoparticules d'oxyde de cérium comprennent, en tant que stabilisant, un acide aminé basique, une amine alicyclique, un composé hétérocyclique aromatique qui comprend un atome d'azote dans sa structure cyclique, un polymère qui a un squelette d'amine hétérocyclique, ou un composé de bore, et sont caractérisées en ce que l'APHA d'une dispersion de 1 % en masse des particules n'est pas supérieur à 400. La composition de résine et le matériau fibreux comprennent lesdites nanoparticules et ont une faible coloration.
