| 20100019204 | SURFACE TREATMENT METHOD FOR NANOPARTICLES - The present invention relates to a surface treatment method for nanoparticles. The present invention particularly relates to a surface treatment method for nanoparticles, which increases the dispersion ability of the nanoparticles in a solvent, and in which a mixture made of a polyvalent acid and a nitrogen-containing base, such as an amine, or a salt of a polyvalent acid and a nitrogen-containing base, such as ammonium salt, or also a corresponding betaine, is used. The present invention also relates to surface-modified nanoparticles, which can be obtained by the inventive method. | 01-28-2010 |
