While phase change material (PCM)-encapsulated polyHIPE monoliths are advantageous for latent heat storage, brittleness and time-consuming preparation hinder their wide application. Herein, we report the rapid fabrication of closed-cell, flexible monoliths through emulsion templating in seconds through ammonia-catalyzed interfacial thiol-Michael addition. Using an organic PCM (octodecane, OD) as the dispersed phase, OD-encapsulated monoliths with flexibility were fabricated for the first time. The monoliths exhibited high flexibility at temperature over 30 °C and robust compressive property. The OD-encapsulated monoliths possessed extremely high heat capacity (up to 213 J/g, ~90% pure OD), and high reusability/stability (without obvious deterioration in heat capacity after 100 heating/cooling cycles). The feature that combines the rapid synthesis, high flexibility, mechanical robustness, high heat capacity and good reusability/stability enabled the OD-encapsulated monoliths to be excellent candidates for latent heat storage.

尽管相变材料（PCM）封装的polyHIPE整料对于潜热存储是有利的，但脆性和耗时的制备阻碍了它们的广泛应用。在本文中，我们报告了通过氨催化的界面硫醇-迈克尔加成反应在数秒内通过乳液模板快速制备闭孔，柔性整料的方法。使用有机PCM（十八烷，OD）作为分散相，首次制备了具有柔韧性的OD封装的整体材料。整料在超过30°C的温度下显示出高柔韧性和强大的压缩性能。OD封装的整料具有极高的热容（高达213 J / g，约OD的90％）和高可重复使用性/稳定性（在100个加热/冷却循环后热容没有明显降低）。结合了快速综合的功能，
