Abstract

The invention relates to surface-modified particles, more particularly inorganic-based particles having reactive surfaces, more particularly surfaces containing silane-reactive and/or siloxane-reactive groups, preferably hydroxyl-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 particularly been reacted on their surface with a polysiloxane-based modifier, preferably with the formation of chemical bonds, more particularly covalent bonds, and also to a method of producing these surface-modified particles.
