摘要: Abstract Inspired by mineralization, a series of composite membranes with polymer–nanoparticle hybrid active layer were prepared via generic and facile approach in this study for solvent resistant nanofiltration. Polyethyleneimine (PEI) was employed as polymer matrix, the –NH 2 /–NH– groups which catalyzed inorganic precursor (tetraethoxysilane/tetra-n-butyl titanate) to synthesize nanoparticles (silica/titania) tunable structure. Then, layers covalently cross-linked further enhancing thermal structural stabilities membranes. The composition microstructure investigated through Fourier transform infrared spectroscopy, scanning electron microscope, thermogravimetric analysis, contact angle measurement. nanofiltration performances terms uptake, area swelling, flux, rejection measured using n-heptane, toluene, butanone, ethyl acetate, isopropanol solvents, well polyethylene glycol solute. results suggested that presence endowed membrane excellent resistance above solvents (area swelling below 6%). Meanwhile, dramatically elevated while remaining sufficient flux promising long-term operation stability. Moreover, influence type nanoparticle on evaluated detail.
