相变材料作为太阳能、工业废热和余热的储能材料，受到了广泛的关注。在这里，我们提出了一种简单的和可扩展的合成PCM-碳泡沫复合材料，通过使用聚异氰脲酸酯（PIR）泡沫衍生的碳泡沫作为多孔载体。碳泡沫材料独特的三维分子构型使复合材料具有高的PCM负载能力、优异的形状稳定性和热可靠性以及化学稳定性。采用化学活化法制备的泡沫炭比表面积高达1968 m2/g，相变储能容量高达90.8wt%，储能容量高达105.2J/g。先进的表征表明，碳泡沫的总孔体积决定PCM的负载能力以及复合材料的储能性能。本研究为回收利用建筑行业中广泛使用的PIR泡沫材料，制备具有成本效益的相变储能复合材料提供了一条潜在的途径。
Phase Change Materials (PCMs) has gained considerable interest for storing thermal energy originating from the solar irradiation, industrial waste heat and surplus heat. Here, we present the facile and scalable synthesis of PCM-carbon foam composites by using polyisocyanurate (PIR) foam derived carbon foam as porous support. The unique 3D molecular configuration of the carbon foam materials embedded the composites with high PCM loading capacity, excellent shape stabilization and thermal reliability and chemical stability. The carbon foams prepared by facile chemical activation method with high surface area up to 1968 m2/g exhibit high PCM loading capacity of up to 90.8 wt% and excellent energy storage capacity of up to 105.2 J/g. Advanced characterization demonstrated that the total pore volume of carbon foam governs the PCM loading capacity as well as the energy storage performance of the composites. This work provides a potential pathway to recycle PIR foams, which have been widely used in construction industry, by producing cost-effective PCM composites for thermal energy storage.
