HEAT-ABSORBING/HEAT-RELEASING CAPSULE, METHOD FOR PRODUCING THE SAME, HEAT-ABSORBING/HEAT-RELEASING CAPSULE DISPERSION AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To further improve heat-absorbing/heat-releasing performance by increasing the content of a phase-transfer substance in a capsule while using a phase-transfer substance to be dissolved in a water-soluble solvent having a high melt/solidification latent heat advantageous for improving heat-absorbing/heat-releasing performance.

SOLUTION: The heat-absorbing/heat-releasing capsule 10 is equipped with a filmy capsule wall body 1 forming a closed space in the inside and a phase-transfer substance 2 that is dissolved in a water-soluble solvent as a sealed substance sealed in the closed space of the capsule wall body 1. When the total of the heat-absorbing/heat-releasing capsule is 100 vol.%, the phase-transfer substance 2 is contained in≥70 vol.% volume ratio.
