反渗透复合膜最新研究进展

Progress on thin-film composite(TFC)reverse osmosis membrane

反渗透膜在海水淡化、超纯水制备、污水处理、制药及生物技术等领域得到了广泛应用.目前,最成功的反渗透膜是通过界面聚合方法制备的以交联聚酰胺为分离皮层的复合膜.交联聚酰胺皮层的结构和性质对最终反渗透膜的分离性能起关键作用.本文简要介绍了界面聚合复合膜的形成过程和结构、新型界面聚合功能单体、界面聚合反应添加剂、纳米杂化反渗透复合膜、高耐氯氧化性反渗透膜,以及反渗透复合膜表征方法创新等方面的研究进展和发展趋势.

Reverse osmosis （RO） membranes have been widely used in seawater desalination, ultrapure water production, wastewater treatment, pharmaceutical and biological industries. The whole aromatic polyamide thin-film composite membrane （TFC） is the most successful reverse osmosis membrane nowadays. The performance of reverse osmosis membrane is decided by the physical structures and chemical properties of the ultra-thin polyamide layer. Progress on reverse osmosis composite membrane, including the formation process of interfacially polymerized composite membrane, novel monomers used for interracial polymerization, the additives, nano hybrid reverse osmosis membrane, highly chlorine-tolerant reverse osmosis membrane and new characterization methods for reverse osmosis membranes are introduced briefly in this review.
