Development of CuO particles onto bacterial cellulose sheets by forced hydrolysis: A synergistic approach for generating sheets with photocatalytic and antibiofouling properties

CuO was successfully prepared on bacterial cellulose paper as a nanocomposite using the forced hydrolysis technique. The composite paper presented outstanding photocatalytic and antibacterial properties. The effect of pH from 7 to 11 on CuO formation on bacterial cellulose was tested. The structural properties of the composite were investigated by Fourier transform infrared spectroscopy and X-ray diffraction. Thermogravimetric analysis showed that the composite has a thermal resistance of up to 200 degrees C. Scanning electron microscopy showed that bacterial cellulose existed as a network and that CuO particles filled the spaces in the network. Energy-dispersive and mapping analysis also showed the optimal uniformity and distribution. The composite paper will act as the prototype for both photocatalyst and antibacterial properties for paper-based technology. (C) 2019 Elsevier B.V. All rights reserved.
