TAILORED DISPERSION AND FORMATION OF INTEGRATED PARTICLE SYSTEMS VIA PH RESPONSIVE GROUPS

摘要

This invention provides methods and technology related to increased hiding power of a coating through mediating the interaction of the pigment with other system components including but not limited to other pigment particles, latex paint particles, latex binding particles, and organic or inorganic hollow particles. Organization and spacing are tailored via pH sensitive functionalities hosted on ligands or polymeric spacers that are located at/within the surface of one of the components.

主权项

1. A process for making a pre-integrated inorganic system component dispersion comprising:
a. Providing i) one or more binding particles selected from the group consisting of solid inorganic particles, hollow inorganic particles, or combinations thereof, wherein one or more binding particles has on its surface one or more spacers comprising one or more pH responsive groups, wherein the one or more pH responsive groups are selected from the group comprising sulfonic acids, phosphonic acids, carboxylic acids, amines, boronic acids, salts and esters thereof, or combinations thereof, ii) one or more second inorganic particles comprising one or more target sites, and a solvent; and b. Creating a dispersion comprising the one or more binding particles, the one or more second inorganic particles, and the water solvent at a first pH to prevent formation of chemical bonds between the one or more pH responsive groups and the one or more target sites.
