Robust fabrication of thin film polyamide-TiO 2 nanocomposite membranes with enhanced thermal stability and anti-biofouling propensity

摘要: The development of nano-enabled composite materials has led to a paradigm shift in the manufacture high-performance nanocomposite membranes with enhanced permeation, thermo-mechanical, and antibacterial properties. major challenges successful incorporation nanoparticles (NPs) polymer films are severe aggregation NPs weak compatibility polymers. These two phenomena lead formation non-selective voids at interface NPs, which adversely affect separation performance membrane. To overcome these challenges, we have developed new method for fabrication robust TFN reverse osmosis membranes. This approach relies on simultaneous synthesis surface functionalization TiO2 an organic solvent (heptane) via biphasic solvothermal reaction. resulting stable suspension heptane was then utilized interfacial (in-situ) polymerization reaction where were entrapped within matrix polyamide (PA) 10 nm effectively incorporated into thin PA layer improved thermal stability anti-biofouling properties features make our synthesized potential candidates applications treatment high-temperature streams containing biomaterials is desirable.
