TEMPERATURE SENSITIVE CAPSULE AND METHOD OF PREPARING THE SAME

摘要

The present invention relates to a temperature sensitive capsule capable of controlling flexibility and brittleness depending on a change in temperature, and a method for preparing the same. The temperature sensitive microcapsule according to the present invention can control the release properties of a shell depending on a change in temperature by dispersing a phase change material into the shell. In other words, the shell surrounding the core of the capsule according to the present invention has flexibility at a temperature higher than the freezing point of the phase change material but has brittleness at a temperature lower than the freezing point. It is possible to provide a microcapsule that may be broken with ease under external impact by using the phase change material dispersed in the shell. According to the microcapsule of the present invention, it is possible to break the shell in a desired range of temperatures by selecting a phase change material adequately, and thus can release the material stored therein.
