Bacterial cellulose membranes find extensive applications in industries involving water purification, wastewater treatment, and biomedical uses. Nevertheless, prevailing membranes suffer from drawbacks like water flow hindrances and fouling susceptibility. Hence, the pressing need for more efficient and robust BC membranes. This study aims to assess the impact of a hybrid treatment involving Copper Oxide nanoparticles (CuO-NPs) and Graphene Oxide (GO) on bacterial nanocellulose membranes. The research employed two treatments: (1) control (BNCA), and (2) Bacterial cellulose infused with 0.5 wt% CuO-NPs/GO. The nanocellulose production involved a high-pressure homogenizer, followed by acetate nanocellulose synthesis and nanocomposite membrane functionalization with CuO nanoparticles. SEM, FTIR, and XRD analyses characterized the membranes. Successfully formed seaweed-derived bacterial cellulose had a thickness of 1-3 cm. Characterization showed it belonged to Cellulose type I with a crystalline degree ranging from 82.3% to 83.1%. FTIR analysis of dry BNCA membranes indicated changes in transmittance at 1738, 1554, and 764 cm−1 due to CuO-NPs/GO addition, altering the O-H bond in bacterial cellulose. Based on the results of the above research, it is evident that the Membrane Reinforced with CuO-NPs/Graphene Oxide has been successfully developed and holds potential as a water nanofiltration system. © 2024 Institute of Physics Publishing.
