本文提出了一种简单的方法，通过相转化技术在混合基质膜表面形成纳米尺寸的图案，其中纳米颗粒的量逐渐增加。当饲料蛋白溶液流向垂直于图案化线的方向时，可以减轻牛血清白蛋白（BSA）超滤的污染，而当流向平行于图案化方向时，污染表面被更有效地洗涤。所提出的方法允许以较低的成本在大的膜面积的表面上控制图案。此外，膜表面的亲水性可以通过添加亲水性纳米颗粒来增加，这也有助于减轻结垢。(C)2013爱思唯尔有限公司版权所有。
This paper presents a simple method to form a nano-sized pattern on the surface of mixed matrix membranes with an increasing amount of nanoparticles incorporated in the polymer matrix through phase inversion technique. The fouling by bovine serum albumin (BSA) ultrafiltration could be mitigated when the feed protein solution flowed to the direction perpendicular to the patterned lines while the Fouled surface was washed more effectively when the How was parallel to the patterned direction. The proposed method allows pattern to be controlled on the surface of a large membrane area at a lower cost. Also, hydrophilicity of the membrane surface can be increased by adding hydrophilic nanoparticles, which also contributes to fouling mitigation. (C) 2013 Elsevier B.V. All rights reserved.
