摘要
The fabrication of metal organic frameworks (MOFs) on the various supported substrates, especially lightweight and flexible substrates have been attempted for many years. In recent years, zeolitic imidazole frameworks (ZIF-8) and fabric composites have attracted researchers’ interest, but the combination of two-dimensional zeolitic imidazolate framework (ZIF-L) and fabric rarely involves. Aiming to this, a two-dimensional ZIF-L was successfully fixed on modified cotton fabrics by a facile in-situ growing method under the same experimental conditions as the synthesis of ZIF-8, and ZIF-L coated cotton fabric (CF-NH2@ZIF-L) has multiple properties like indoor formaldehyde purifying capability, excellent antibacterial properties and good UV protection. The cotton fabric was first modified with 3-aminopropyltrimethoxysilane (APTMS) and then the ZIF-L crystal films were in situ growth on the amine modified cotton fibers at room temperature in aqueous phase. The CF-NH2@ZIF-L fabric demonstrates excellent antibacterial properties and its antibacterial activity against Escherichia coli and Staphylococcus aureus is 99.52 % and 99.89 % respectively. In addition, it also has good UV protection and indoor formaldehyde purifying capability. The multifunctional cotton fabric prepared by this method can be viewed as a potential candidate used as decorative textile or air purification material.
