Conventional water treatment polyamide nanofiltration (NF) membranes often suffer from the degradation of sodium hypochlorite (NaOCl) in sewage or during the process of membrane cleaning and deteriorate the separation performance, which significantly increases the treatment cost. Herein, a novel polyacrylate composite NF membranes were prepared by interfacial polymerization using oligomeric phenolic resin (OPR) and trimesoyl chloride (TMC) as aqueous and organic phase monomer respectively on the polyethersulfone (PES) ultrafiltration supporting membranes. The fabrication parameters, including the pH of the aqueous solution, reaction time and the concentration of the monomer, on the performance of the composite NF membranes were optimized. A series of characterization indicated that the surface of the NF membranes was negatively charged, the molecular weight cut-off (MWCO) and the pore diameter of the polyacrylate membrane were 400 Da and 0.47 nm, respectively. At the optimized preparation conditions, the NF membrane exhibited high Na₂SO₄ rejection of 98.2% and water flux of 2.42L·m⁻²·h⁻¹·bar⁻¹, which was superior to most of the polyacrylate NF membranes reported in recent years. Compared with the polyamide membrane, the prepared polyacrylate membrane demonstrated better chlorine-resistant property and still maintained 92.0% Na₂SO₄ rejection after being treated with NaOCl solution. Moreover, the NF membrane preserved excellent long-term operation stability. The chlorine-resistant NF membrane constructed from OPR monomer has a broad application prospect in the field of high chlorine wastewater treatment.

常规的水处理聚酰胺纳米过滤（NF）膜通常会遭受污水中或膜清洗过程中次氯酸钠（NaOCl）的降解，并使分离性能恶化，从而大大增加了处理成本。在此，通过低聚酚醛树脂（OPR）和均苯三甲酰氯（TMC）分别作为聚醚砜（PES）超滤支持膜上的水相和有机相单体，通过界面聚合制备了新型聚丙烯酸酯复合NF膜。优化了制备参数，包括水溶液的pH值，反应时间和单体浓度，对复合NF膜的性能进行了优化。一系列表征表明NF膜的表面带负电，聚丙烯酸酯膜的截留分子量（MWCO）和孔径分别为400 Da和0.47 nm。在优化的制备条件下，NF膜表现出高Na₂ SO ₄截留率为98.2％，水通量为2.42L·m ^-2 ·h ^-1 ·bar ^-1，优于近年来报道的大多数聚丙烯酸酯NF膜。与聚酰胺膜相比，制备的聚丙烯酸酯膜表现出更好的耐氯性，并且在用NaOCl溶液处理后仍保持92.0％的Na ₂ SO ₄截留率。此外，NF膜保留了出色的长期运行稳定性。由OPR单体构成的耐氯NF膜在高氯废水处理领域具有广阔的应用前景。
