| Abstract: | The research focus and application prospects of silicone phase change materials were reviewed. Through in-situ variable temperature XRD technology, the phase structure changes of silicone phase change materials in the process of changing temperature were revealed. It shows that in warning up, silicone phase change materials can transit from amorphous to crystalline and increase electrical conductivity, while transit from crystalline to amorphous in cooling and decrease electrical conductivity, which plays a key role in the implementation of phase change memory storage and erasure technologies. |
