摘要： 随着反渗透膜应用的普及化和广泛化，提升其渗透性能成为了当下的迫切追求。为进一步改善以间苯二胺（MPD）与均苯三甲酰氯（TMC）为反应单体的芳香聚酰胺反渗透膜的分离性能以及表面形貌，从水相浸润时间、油相反应时间、热处理温度和时间、MPD及TMC的添加量、以及二甲亚砜（DMSO）的添加量等方面进行了研究，得到具有均一形貌的高渗透性芳香聚酰胺反渗透膜。通过对芳香聚酰胺反渗透膜进行性能评价、扫描电子显微镜（SEM）以及傅里叶红外变换光谱仪（FT-IR）等测试。结果表明：改善工艺参数后得到的反渗透膜拥有良好的渗透性能、分离性能以及表面形貌。

Abstract: With the popularization and widespread application of reverse osmosis membranes, improving their permeation performance has become an urgent pursuit nowadays. To further improve the separation performance and surface morphology of aromatic polyamide reverse osmosis membranes with m-phenylenediamine (MPD) and trimesoyl chloride (TMC) as reaction monomers, this paper investigates the aqueous phase infiltration time, oil phase reaction time, heat treatment temperature and time, the addition amounts of MPD and TMC, and the addition amount of dimethyl sulfoxide (DMSO) to obtain highly permeable aromatic polyamide reverse osmosis membranes with homogeneous morphology. The aromatic polyamide reverse osmosis membranes were tested by performance evaluation, scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). The results showed that the reverse osmosis membranes obtained by improving the process parameters have good permeation performance, separation performance and surface morphology.
Key words: aromatic polyamide; reverse osmosis; permeability; rejection; reaction parameters.
