This project seeks to develop advanced mixed-matrix composite membranes specifically designed for the pervaporation separation of solvent-laden wastewater, responding to the urgent need for membranes characterized by high efficiency, selectivity, and robustness in demanding industrial settings. It is organized into four phases. The first stage focuses on optimizing membrane fabrication parameters, which encompass the selection of the polymer matrix and inorganic nanofillers, the refinement of fabrication methods, and the adjustment of polymer and nanofiller concentrations. In the second phase, nanofillers will be subjected to additional modification to fine-tune membrane structure and improve compatibility with the polymer matrix prior to their integration into the membrane. The third phase entails a thorough characterization of the fabricated membrane and synthesized nanofillers to provide an understanding of the material's structural properties. This analysis confirms the compatibility of nanofillers within the polymer matrix and to evaluate potential performance consequences. The concluding phase of this research will involve the application of synthesized mixed matrix membranes to treat industrial and domestic wastewater. The efficacy of these membranes will be evaluated through pervaporation separation experiments, with a focus on assessing their stability under challenging conditions.
