我们研究了一种由膨胀石墨(EG)/石蜡/聚二甲基硅氧烷(PDMS)组成的太阳能相变材料(SPCM)，该材料不仅可以进行太阳能热转换，还可以释放/储存热量能量。在阳光照射下，SPCM有效地收集光能并将其转化为热能，用于后期防冰/除冰。为了准备无光期，例如，在晚上，转换的热能可以通过相变存储在SPCM中。这样，当需要保持表面温度不结冰时，就可以释放能量。

Herein, we investigate a solar phase-change material (SPCM) that consists of expanded graphite (EG)/paraffin/polydimethylsiloxane (PDMS), which can not only perform the solar-thermal conversion but also release/store thermal energy. Under sunlight, the SPCM effectively collects and converts the light energy into thermal energy for later antiicing/de-icing. To prepare for a no-light period, e.g., in the evening, the converted thermal energy can be stored in the SPCM using a phase transition. In this way, the energy can be released when needed to keep the temperature of a surface from freezing.
