Tailoring growth of MOF199 on hierarchical surface of bamboo and its antibacterial property

Bamboo, as a fast-grown forest resource, can be functionalized by metal–organic frameworks (MOFs) with various potential applications. However, the stability of MOFs immobilized on bamboo surface remains to improved. In this work, MOF199, known HKUST-1, was in situ anchoring moso via regulating pretreatment and green two-step synthesis route. The route completed under room temperature both precursor solutions reused. results indicated that, collaboration delignification carboxymethylation bamboo, dense well-dispersed MOF coating successfully synthesized, adhesion between MOF199 also Besides, quantity size tailored tunning carboxyl groups pretreated concentration copper nitrate solution. More importantly, show that formation carboxyl-copper (II) complex served nucleation sites for growth crystals, which essential prepare uniform layers. endowed good antibacterial activity against Escherichia coli. This method provides facile practical strategy designing coated woody materials.
