  • CHEMOMECHANICAL MANUFACTURE OF FUNCTIONAL COLLOIDS
    Publication number: 20110288183
    Abstract: A method for producing a functional colloid during which particles are reactively fragmented in a mechanical manner in a dispersant in the presence of a modifying agent so that the modifying agent is chemically bound, at least in part, to the fragmented colloid particles.
    Type: Application
    Filed: June 9, 2011

  • Process for the Production of Nanoparticles with Tailor-Made Surface Chemistry and Corresponding Colloids
    Publication number: 20090004098
    Abstract: A process for the production of a suspension of crystalline and/or densified, surface-modified nanoscale particles in a dispersant. The process comprises: (a) heat-treating a suspension of amorphous or semicrystalline, non-surface-modified nanoscale particles in a first dispersant to obtain crystallized and/or densified particles; and (b) mechanically activating, in the presence of at least one modifying agent, the particles obtained according to (a) as a suspension in the first dispersant or in a different dispersant to obtain a suspension of crystalline and/or densified nanoscale particles which are surface-modified by the at least one modifying agent.
