Poly (2-hydroxyethyl methacrylate) grafted silica (SiO2) nanoparticles (SiO2-g-PHEMA NPs) were prepared via surface-initiated activators regenerated by electron transfer atom transfer radical polymerization. Then the synthesized NPs were utilized as a hydrophilic additive for fabrication polyethersulfone (PES)/SiO2-g-PHEMA organic-inorganic composite membranes. The transmission electron microscope results confirm that the SiO2-g-PHEMA NPs uniformly dispersed in the casting solution and tend to migrate toward the membrane top surfaces. As a result, the hydrophilicity of the composite membranes is significantly improved (the contact angle decreases from 84.5° to 71.9°). The membrane exhibits the highest pure water flux and oil flux around 208.68 L/(m2·h) and 86.86 L/(m2·h) when the SiO2-g-PHEMA dosage is 1% (in mass), the pure water flux and oil flux of the unmodified PES membrane around 64.10 L/(m2·h) and 11.09 L/(m2·h). Compared to the unmodified PES membrane, the flux recovery ratio increases from 45.74% to 78.32%, suggesting the fouling-resistance of the composite membranes is greatly improved. Furthermore, the SiO2-g-PHEMA NPs exhibit good stability due to the physical intertwisting interaction between the PHEMA chains and PES chains, indicating that this material has a potential application prospect.
