Engineering Hygroscopic MOF‐Based Silk Via Bioinspired Interfacial Assembly for Fast Moisture Manipulation

Metal-organic frameworks (MOFs) have emerged as exceptional moisture sorbents in low humidity conditions. However, their typical powdered form often results in agglomeration, impeding water diffusion kinetics and practical handling. To enhance the accessibility and diversify the integration of MOFs, a universal and scalable bionic interfacial assembly method is introduced for fabricating MOF-based silk. The resulting silk, enriched with a high content of MOF-303, demonstrates a significant water adsorption capacity of 315.1 mg g
