The Technology

A family of continuous porous polymers, generally known as polyHIPEs, have been synthesized using high internal phase emulsions (HIPEs) as templates for the porous structure. This composition-of-matter having microscopic closed-cell capsules (either hydrophobic and hydrophilic) can be utilized for various applications: encapsulating micron-scale droplets of liquids, gels, or molten salts; sustained release of substances such as fertilizers; encapsulating phase change materials (PCMs) which can store and release large amounts of thermal energy.
