Abstract
Provided is a latent heat transfer material that is micro-encapsulated, said material exhibiting superior mechanical strength and heat resistance. A production method for the latent heat transfer material that is micro-encapsulated in a hard shell comprises: 1) a step in which a perforate hollow silica particle is manufactured; 2) a step in which the phase change material is sealed inside the perforate hollow silica particle by inserting the perforate hollow silica particle in a molten solution of the phase change material and repeatedly subjecting the same to vibrations such as ultrasound oscillations; 3) a step in which the perforate hollow silica particle having the phase change material sealed within is washed in a saturated aqueous solution of the phase change material; and 4) a step in which perhydropolysilazane is used to coat the outer shell of the perforate hollow silica particle with silica.
