Therefore, it is necessary to develop ways for additional stabilization of MOFs, in particular on the surface of primary substrates. Here we studied the formation of copper-containing metal-organic framework HKUST-1 in the structure of cotton and polyethylene terephthalate fabrics using three approaches differing in the way of introduction of copper ion precursor into the reaction mixture. Pre-impregnation of the fabrics with a solution of a metal ion precursor salt followed by assembly of MOF in an aqueous ethanol solution of trimesic acid was shown to be the optimal approach for the self-assembly of HKUST-1 on the surface of cotton and polyethylene terephthalate fabrics. The specific surface area and HKUST-1 contents in the obtained materials were 198–259 m2/g and 12–15.8 wt %, respectively. The composite based on polyethylene terephthalate fabric was shown to be more stable to mechanical impact than the cotton-based material.
