在本文中，一些新的事件上的芳香族聚酰胺薄膜复合（TFC）膜的表面形态结合其固有的化学性质进行了论证。此外，详细、定量地了解微观表面特征对于控制水渗透性和最终开发高性能隔膜是必不可少的。表面粗糙度和表面积主要受交联和/或与氢键形成无关的游离酰胺基团的存在或不存在的影响，这反过来又有助于水渗透性。© 1999 John Wiley & Sons，Inc.聚合物科学杂志B：聚合物物理37：1429 - 1440，1999
In the present article, some new events on the surface morphology of the aromatic polyamide thin-film-composite (TFC) membranes were demonstrated in con- junction with their inherent chemical nature. In addition, the detailed, quantitative understanding of the microscopic surface features was shown to be essential in con- trolling the water permeability and eventually developing the high performance mem- branes. The surface roughness and the surface area were mainly affected by the existence or nonexistence of the crosslinking and/or the free amide groups not pertinent to the formation of the hydrogen bonding, which in turn contributed to the water permeability. © 1999 John Wiley & Sons, Inc.
