Abstract
It is desirable that the heat storage materials for nano and micro satellites have the characteristic of not phase change but crystal transformation for the heat storage. Trans-1,4-polybutadien has the desirable characteristic of crystal transformation at the heat storage temperature. The heat storage and release tests were conducted on the ground and in orbit. It is clarified that the heat storage and release characteristics do not change in heat storage and release cycle of 300 times and Trans-1,4-polybutadien can storage and release heat in orbit.
