Abstract
The method for low temperature microencapsulation of phase change materials or other components includes the following steps: (a) preparing a phase change emulsion including droplets of at least one active phase-change material in water with a surfactant; (b) adding a monomer of at least one encapsulating agent; (c) introducing the phase change emulsion into a UV reactor while stirring the emulsion; and (d) initiating the photo polymerization of monomers using at least one UV lamp inside the UV reactor for photo polymerization until the phase change material is encapsulated within a polymeric shell to form microcapsules. The microcapsules obtained by this process may have a diameter between about 0.5 to about 2 μm. Other sizes can also be obtained by changing stirring speed of the emulsion.
