Interface molecular mineralization enables green, scalable fabrication of MOF-fabric composites

Abstract

Metal-organic frameworks (MOFs) have emerged as a favored component in composites owing to their high porosity and synthetic tunability. However, loading MOF powders into a polymer matrix to form composites often relies on organic solvents and rigorous manufacturing processes. Here, we propose a biomimetic mineralized molecular engineering strategy, enabling robust, large-scale fabrication of MOF-fabric composites without organic solvents. This strategy allows MOF nodes to be embedded between highly elastic state polymer molecular chains, achieving strong physical anchoring. The preparation process realizes a significant reduction in carbon emissions (30%-50%) and high production efficiency (10 kg/h) while maintaining excellent fixation fastness, including resistance to washing (over 25 times), rubbing (over 100 times), and light (over 12 h). Furthermore, the applications of MOF-fabric composites in personal protective equipment are demonstrated, including organic gas adsorption, UV protection, and antibacterial. Our work provides a sustainable pathway towards the practical application of MOF-fabric composites.
