分子太阳能热（MOST）材料可以有效地捕获太阳能并根据需要将其作为热量释放，是未来个人热管理（PTM）应用的有希望的候选者，最好以织物的形式出现。然而，由于分子材料的低能量密度及其从织物中的泄漏，开发具有高能量存储容量和稳定工作性能的大多数织物仍然是一个重大挑战。本文报道了一种高效、坚固的用于PTM的MOST织物，该织物使用含有氮吡唑的微胶囊，带有深紫外线过滤壳。MOST织物可以共同收集太阳能和热能，实现了高效的光充电和光放电（>90%的光转换），2.5 kJ m - 2的高能量密度，以及以月为尺度的长期存储可持续性。此外，它可以经历多次洗涤、摩擦和充电循环，而不会显著损失储能容量。这种MOST微胶囊策略很容易用于太阳能热灸的MOST织物的可扩展生产。这一成果为具有高储能性能和鲁棒性的可穿戴MOST材料在PTM中的应用提供了一条有希望的途径。
Molecular solar thermal (MOST) materials, which can efficiently capture solar energy and release it as heat on demand, are promising candidates for future personal thermal management (PTM) applications, preferably in the form of fabrics. However, developing MOST fabrics with high energy‐storage capacity and stable working performance remains a significant challenge because of the low energy density of the molecular materials and their leakage from the fabric. Here, an efficient and robust MOST fabric for PTM using azopyrazole‐containing microcapsules with a deep‐UV‐filter shell is reported. The MOST fabric, which can co‐harvest solar and thermal energy, achieves efficient photocharging and photo‐discharging (>90% photoconversion), a high energy density of 2.5 kJ m−2, and long‐term storage sustainability at month scale. Moreover, it can undergo multiple cycles of washing, rubbing, and recharging without significant loss of energy‐storage capacity. This MOST microcapsule strategy is easily used for the scalable production of a MOST fabric for solar thermal moxibustion. This achievement offers a promising route for the application of wearable MOST materials with high energy‐storage performance and robustness in PTM.
