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