摘要:
Bead comprising at least two non-agglomerated solid nanoparticles of core structure comprising only a solid core, or of core-shell structure comprising a solid core surrounded by a solid envelope or shell made up of an inorganic material, said nanoparticles being coated with a non-porous metal oxide.Process for preparation of the said bead.Material such as glass, a crystal, a ceramic or a polymer containing said beads.
摘要:
The invention seeks protection for a novel method for the surface functionalization of solid materials with one or more active ingredients intended to confer specific properties thereon, such as anti-UV, fluorescence or coloring properties.
摘要:
The invention relates to nanoparticles having a core that is fully or partially formed by at least one UV-absorbing organic compound in crystallized form and coated with an outer layer formed by at least one hydrophilic polymer, said UV-absorbing organic compound(s) and hydrophilic polymer(s) being associated in a weight ratio of organic compound(s) to hydrophilic polymer(s) varying between 0.2 and 0.4.
摘要:
The present invention relates to a vitreous material possessing visual effects, particularly of fluorescence, when it is lit by ultraviolet light in the visible spectrum. These glasses are particularly applicable to the manufacture of decorative objects.
