中化新网讯 在太阳能、工业废热利用及电子设备热管理等领域，高效的热能储存材料至关重要。相变 材料因能在相变过程中吸收或释放大量潜热被视为理想选择，但其普遍存在的低导热性问题严重限制了 储、放热速率。近日，浙江大学教授范利武和博士李梓瑞团队提出一种通过增强氢键来恢复复合相变材 料能量密度的新策略，相关论文发表在《先进材料》上。 这种策略基于商业化易得的羟基化纳米填料，易于推广至多元醇、脂肪酸、结晶水合盐等多种相变材料 体系，为开发下一代高性能、长寿命的热能储存与管理系统提供切实可行的技术路径，有望在可再生能 源集成、工业节能及电子热管理等领域发挥作用。 实验表明，相较于未改性的石墨烯，使用羟基化石墨烯可使赤藓糖醇复合材料的潜热得到显著恢复。该 策略为开发兼具高能量密度与高功率密度的高性能复合相变材料提供了新思路。 ...
