20090061230 | Synthesis of Titanium Dioxide Nanoparticles - The present invention relates to a process for the production of titanium-containing oxide particles having an average primary particle size of 25 nm or less, which comprises the reaction of a hydrolysable halide-containing titanium compound with water in a reaction mixture comprising a polyol, and the particles obtainable thereby. The claimed method is suitable for an industrial upscale and allows the formation of concentrated stable and transparent dispersions in water without the aid of dispersing agents such as surfactants. | 03-05-2009 |
20090099288 | Stabilization of organic polymers against free radicals - The invention concerns the use of cerium dioxide, especially in the form of discrete cerium dioxide particles with particle sizes in the range from 0.005 to 150 μm, as inorganic radical trap to stabilize organic polymers, especially in the form of polymer-based formulations, varnishes, paints, coating compounds, or the like, against their photochemically, thermally, physically and/or chemically induced degradation by free radicals, especially against the effect of UV, advantageously in an optional combination with at least one UV-absorber and/or at least one additional radical trap. The radical-induced degradation of the organic polymers is effectively prevented by the use of cerium dioxide without the cerium dioxide itself becoming degraded. If a combination of cerium dioxide with an additional UV-absorber or radical trap is used, its effectiveness is extended through the presence of the cerium dioxide. | 04-16-2009 |
20100059720 | DISPERSION METHOD - The invention relates to a method of dispersing carbon nanotubes (CNTs) in a continuous phase, especially in at least one dispersion medium, the carbon nanotubes, especially without prior pretreatment, being dispersed in a continuous phase, especially in at least one dispersion medium, in the presence of at least one dispersant (dispersing agent), with introduction of an energy input sufficient for dispersing, and also to the dispersions that are obtainable in this way, and to their use. With the method of the invention it is possible for the carbon nanotubes (CNTs) to be dispersed in high concentrations and with high storage stability. | 03-11-2010 |
20120190787 | REACTIVE SYSTEMS - Reactive system comprising at least one component (I) composed of particles in very finely divided form present in a liquid phase of at least one further component (II) with which component (I) is capable of reacting following activation through energy supply, wherein component (I) is not soluble in component (II), process for preparation and use. | 07-26-2012 |
20120292578 | METHOD FOR PRODUCING COMPOSITE MATERIALS BASED ON POLYMERS AND CARBON NANOTUBES (CNTs), COMPOSITE MATERIALS PRODUCED IN THIS WAY AND USE THEREOF - The invention relates to a method for producing composite materials based on at least one polymer and carbon nanotubes (CNTs), and to composite materials obtained in this manner and the use thereof. | 11-22-2012 |
20140339092 | METHOD FOR PRODUCING ELECTRICALLY CONDUCTIVE STRUCTURES ON NON-CONDUCTIVE SUBSTRATES AND STRUCTURES MADE IN THIS MATTER - The method relates to a method for producing electrically conductive structures on electrically non-conductive substrates and to a method for the electrochemical deposition of metals on substrates, which is suitable in particular for producing metallic structures and/or electroplated plastics. The invention further relates to products obtainable in this way and to the use thereof. | 11-20-2014 |
