使用SEM和AFM两种表面分析技术研究了交联芳香族聚酰胺复合反渗透（RO）膜表层的表面结构及其RO性能之间的关系。结果发现，表层表面结构粗糙的RO膜产生高通量，并且该表面粗糙度与RO膜通量之间存在近似线性关系。因此，交联芳香族聚酰胺复合RO膜的表层表面凹凸被认为是有效RO膜面积的扩大。
The relationship between the surface structures of skin layers of crosslinked aromatic polyamide composite reverse osmosis (RO) membranes and their RO performances have been studied using two surface analytical techniques: SEM and AFM. As a result, it was found that RO membranes whose skin layer surface structures were rough produced high fluxes, and an approximately Linear relationship existed between this surface roughness and RO membrane flux. Accordingly, skin layer surface unevenness of crosslinked aromatic polyamide composite RO membranes is regarded as an enlargement of the effective RO membrane area.
