We report an in situ polymerization strategy to incorporate a thermo‐responsive polymer, poly(N ‐isopropylacrylamide) (PNIPAM), with controlled loadings into the cavity of a mesoporous metal–organic framework (MOF), MIL‐101(Cr). The resulting MOF/polymer composites exhibit an unprecedented temperature‐triggered water capture and release behavior originating from the thermo‐responsive phase transition of the PNIPAM component. This result sheds light on the development of stimuli‐responsive porous adsorbent materials for water capture and heat transfer applications under relatively mild operating conditions.

用于温度介导的水捕获和释放的热响应型MOF /聚合物复合材料。

我们报告了一种原位聚合策略，该策略将热响应性聚合物聚（N-异丙基丙烯酰胺）（PNIPAM）掺入到介孔金属-有机骨架（MOF），MIL-101（Cr）的模腔中。所得的MOF /聚合物复合材料表现出空前的温度触发的水捕获和释放行为，这是由于PNIPAM组分的热响应相变而引起的。该结果阐明了在相对温和的操作条件下用于水收集和传热应用的刺激响应性多孔吸附材料的开发。
