MICROCAPSULES, THEIR USE AND PROCESSES FOR THEIR MANUFACTURE

摘要

A microcapsule comprising a core containing a hydrophobic liquid or wax w ithin a polymeric shell, in which solid particles insoluble in the hydrophob ic liquid or wax are distributed throughout the core, wherein an oil soluble dispersant polymer is adhered to the surface of the solid insoluble particl es. Processes of obtaining the microcapsules and dispersions of microcapsule s in a liquid are claimed. The microcapsules can be used in a variety of app lications particularly in the field of thermal energy storage. Suitably the microcapsules can be designed to have a particular density and can be used i n the transfer fluids where the density of the microcapsules are the same as the carrier fluid.
