Current reverse osmosis membrane still suffers from permeability/selectivity trade-off, chlorine attack and fouling. To address these problems, a new interlayer-assisted interfacial polymerization (i.e., polyethyleneimine (PEI) interlayer) in the presence of graphene oxide (GO) at various loading was adopted in this work. Their effects on membrane properties and performances were systematically investigated. Results showed that the PEI-interlayered thin film composite (iTFC) membrane exhibited higher pure water permeance (PWP) (1.76 L/m²·h·bar) and NaCl rejection (97.69%) compared to the conventional TFC (cTFC) membrane (1.34 L/m²·h·bar; 96.91%), assigning to the thin and compact PA formed. Performance of iTFC membrane was further enhanced upon inclusion of 0.01 wt/v% GO, producing PEI-interlayered thin film nanocomposite (iTFN-10) membrane with greater PWP (2.66 L/m²·h·bar) without compensating rejection. This was ascribed to the enhanced surface roughness, hydrophilicity and nanochannels created by GO within the PA. The antifouling property of iTFN-10 membrane was comparable with commercial TFC but better than iTFC membrane. Unlike iTFC membrane, the NaCl rejection of iTFN-10 membrane was least deteriorated after chlorination. This membrane also demonstrated better antibacterial properties (E. coli: 44.26% and S. aureus: 77.55%) than commercial membrane (E. coli: 24.68% and S. aureus: 48.98%) due to the presence of amine groups on membrane surface.

当前的反渗透膜仍然存在渗透性/选择性折衷、氯侵蚀和污染等问题。为了解决这些问题，本工作采用了一种新的中间层辅助界面聚合（即聚乙烯亚胺（PEI）中间层），在氧化石墨烯（GO）存在下以不同的负载量进行。系统地研究了它们对膜性能和性能的影响。结果表明，与传统的 TFC (cTFC) 膜相比，PEI 夹层薄膜复合 (iTFC) 膜具有更高的纯水渗透率 (PWP) (1.76 L/m ² ·h·bar) 和 NaCl 截留率 (97.69%)。 1.34 L/m ² ·h·bar；96.91%)，归属于形成的薄而致密的PA。加入 0.01 wt/ v后，iTFC 膜的性能进一步提高^{% GO，生产具有更高 PWP (2.66 L/m 2} ·h·bar) 且无补偿排斥的 PEI 夹层薄膜纳米复合材料 (iTFN-10) 膜。这归因于由 GO 在 PA 中产生的增强的表面粗糙度、亲水性和纳米通道。iTFN-10膜的防污性能与商业TFC相当，但优于iTFC膜。与 iTFC 膜不同，氯化后 iTFN-10 膜的 NaCl 排斥性恶化最小。由于膜表面存在胺基，该膜还表现出比商业膜（大肠杆菌：24.68% 和金黄色葡萄球菌：48.98%）更好的抗菌性能（大肠杆菌：44.26% 和金黄色葡萄球菌：77.55%）.
