Abstract
Trans-1,4-polybutadiene has the attractive characteristic of heat storage by crystal transformation to overcome the difficulty of the thermal design of micro- and nano-satellites. The on-orbit test of the material has been conducted for obtaining the characteristics of heat storage and release in the space environment. The trans-1,4-polybutadiene of 5.5 grams was mounted on Hodoyoshi 4 satellite. The total heat capacity is 440 Joules. It has been confirmed from the on-orbit temperature data that trans-1,4-polybutadiene is able to store and release heat in space more than 1000 cycles. It is shown that the mounted trans-1,4- polybutadiene used the full of heat storage capacity.
