A phase change material prepared microcapsules

Method for preparing microcapsules of phase change material, said method an amount of phase change material monomer mixed with the polymer as an oil phase, the amount of phase change material may be added between 5-80%. Dissolved in the oil phase is added to the deionized water of the surfactants and uniformly dispersed to form an emulsion O / W, and the resulting emulsion was transferred to a hydrothermal reaction vessel, the reaction was cool naturally at 120-200 ℃ 12-24 hours, give complete phase change material coated microcapsule. Particle size of the phase change material in microcapsules prepared according to the present invention within the range of 2-30μm, the method is simple, the coating rate, the initiator may not be added. It can be applied to solar energy, thermal fluid function, fiber insulation and building energy fields.
