This work aimed to investigate the impact of filling MCM-41 and SBA-15 nanoparticles (NPs) on the performance of thin film nanocomposite membranes that applied in reverse osmosis, where SBA-15 is firstly reported here for this purpose. The membranes were prepared via the interfacial polymerization reaction between m-phenylenediamine (MPD) aqueous solution and trimesoyl chloride (TMC)-isooctane solution on a support sheet of polyethersulfone. The reaction time in the presence of NPs was investigated by fixing MPD contact time at 75 s; it was found that 30 s is the optimum TMC contact time. Different loading ratios in the range of 0-0.15 wt% were applied to fill the NPs inside the membranes. Scanning electron microscope (SEM), X-ray Diffractometer (XRD), Fourier-transform infrared spectroscopy (FTIR), and $N_2$ adsorption/desorption tests were used to study the NPs characterizations. While SEM, contact angle, mechanical strain and strength, and membrane performance tests were conducted to study the membranes properties. Results showed that in both nanoparticles (i.e. MCM-41 and SBA-15) cases, 0.1 wt% was the optimum filling percentage. When SBA-15 was loaded, water flux increased from 40 to 74.17 L.m⁻².h⁻¹ (LMH), and NaCl rejection increased from 95.1 to 98.5% comparing with the plain membrane. While when the optimum MCM-41 ratio was loaded, water flux and NaCl rejection raised to 60 LMH and 96.9%, respectively. The performance test conditions were 15 bar, 25 °C, and 2500 NaCl feed concentration.

这项工作旨在研究填充MCM-41和SBA-15纳米颗粒（NPs）对应用于反渗透的薄膜纳米复合膜性能的影响，其中，SBA-15首次在此报道。将膜通过之间的界面聚合反应制备的米上聚醚砜的支撑片苯二胺（MPD）水溶液和均苯三甲酰氯（TMC）异辛烷溶液。通过将MPD接触时间固定在75 s来研究存在NP时的反应时间。发现30 s是最佳的TMC接触时间。施加0-0.15重量％范围内的不同负载率以填充膜内部的NP。扫描电子显微镜（SEM），X射线衍射仪（XRD），傅里叶变换红外光谱（FTIR）和${ñ}_2$吸附/解吸测试用于研究NPs的表征。同时进行SEM，接触角，机械应变和强度以及膜性能测试以研究膜性能。结果表明，在两种纳米颗粒（即MCM-41和SBA-15）中，最佳填充百分比均为0.1 wt％。当装载SBA-15时，与平膜相比，水通量从40增加到74.17 Lm ^-2 .h ^-1（LMH），并且NaCl截留率从95.1增加到98.5％。当加载最佳MCM-41比值时，水通量和NaCl截留率分别提高到60 LMH和96.9％。性能测试条件为15 bar，25°C和2500 NaCl进料浓度。
