Beschreibung
Zusammenfassung:Composite particles that super-aggregates of coated aggregates having low structure carbon black cores and metal/metalloid oxide mantles are described. Coatings containing filler-polymer compositions which have the composite particles as filler, such as curable coatings and cured coatings or films formed therefrom containing the filler-polymer compositions, with combinations of high resistivity, good optical density properties, good thermal stability, high dielectric constant, and good processability, along with their use in black matrices, black column spacers, light shielding elements in LCDs and other display devices, also are described. Inks containing the composite particle are described. Devices having these compositions, components and/or elements, and methods of preparing and making these various materials and products are described. L'invention décrit des particules composites qui sont des super-agrégats d'agrégats enrobés comportant des noyaux de noir de carbone à structure basse et des manteaux d'oxydes de métaux/métalloïdes. L'invention décrit également des revêtements contenant des compositions polymères de remplissage dont le remplissage est constitué des particules composites, de type revêtements durcissables et revêtements durcis ou pellicules ainsi formées contenant les compositions polymères de remplissage, avec des combinaisons de haute résistivité, de bonnes propriétés de densité optique, de bonne stabilité thermique, de constante diélectrique élevée, et de bonne capacité de traitement, ainsi que leur usage dans des matrices noires, des entretoises en colonnes noires, des éléments de protection contre la lumière dans des LCD et autres dispositifs d'affichage. L'invention décrit des encres contenant la particule composite. L'invention décrit des dispositifs comportant ces compositions, composants et/ou éléments, et des procédés de préparation et de fabrication de ces divers matériaux et produits.
