Abstract
A method for the surface coating of CuBTC (Cu3(BTC)2, (BTC=1,3,5-benzenetricarboxylate; HKUST-1) Metal-Organic Framework (“MOF”) nanostructures on natural fibers is disclosed. The surface coating of CuBTC MOF nanostructures is achieved by sequential coating of the natural fibers with a copper precursor solution and a BTC precursor solution under ultrasound irradiation at ambient pressure and temperature. The results indicate a homogeneous coating of the CuBTC MOF nanostructures on the surface of the natural fibers with a narrow size distribution, which impart new properties on the final textile product, such as antimicrobial activity.
