Abstract: Composite materials comprising electrically conductive particles in a form-stable phase change materials (PCMs) are provided. Also provided as radiation sensors incorporating the composites and methods for detecting radiation using the composites. The PCMs comprise crosslinked polyether polyol that undergoes a reversible solid-solid phase change upon heating. Prior to the phase change, the crosslinked polyether polyol comprises microscopic crystalline domains. When the PCM is heated beyond its phase transition temperature these microscopic crystalline domains melt. However, the form-stable PCMs retain their solid form at the macroscopic level.

Abstract translation: 提供了包含形态稳定相变材料（PCM）中的导电颗粒的复合材料。 还提供了包含复合材料的辐射传感器和用于使用复合材料检测辐射的方法。 PCM包括交联的聚醚多元醇，其在加热时经历可逆的固 - 固相变。 在相变之前，交联的聚醚多元醇包括微观结晶域。 当PCM被加热超过其相变温度时，这些微晶结晶域熔化。 然而，形式稳定的PCM在宏观层面保持其固体形式。
