摘要：The invention relates to surface-modified particles, more particularly in organic-based particles having reactive surfaces, more particularly surfaces containing silane-reactive and/or siloxane-reactive groups, preferably hydr oxyl-containing surfaces and/or particles comprising or consisting of metal and/or semi-metal oxides and/or hydroxides, preferably nanoparticles, which on their surface have a polysiloxane-based modifier, having more particularl y been reacted on their surface with a polysiloxane-based modifier, preferab ly with the formation of chemical bonds, more particularly covalent bonds, a nd also to a method of producing these surface-modified particles. The parti cles surface-modified in this way are suitable more particularly for use as fillers and/or for use in any of a very wide variety of systems, more partic ularly in dispersion systems, such as coating materials, for instance paints , inks and the like, and in dispersions of all kinds, in plastics, in foams, in cosmetics, such as in nail varnishes, for example, in adhesives, in seal ants, etc.
