Abstract (en)
[origin: DE102005056622A1] Modified zinc oxide nanoparticles comprise a particle size of 3-50 nm as determined by particle correlation spectroscopy (PCS) or transmission electron microscopy and are modified with silica by a process in which at least one precursor is placed in an organic solvent and grown by addition of at least one modifier, that is a precursor for silica, until the absorption edge in the UV/visible spectrum of the reaction solution reaches the desired value when the process is ended. Independent claims are also included for the following: (A) A dispersion comprising nanoparticles as above; (B) A method of producing the nanoparticles as above;and (C) UV-stabilized polymers as above.
