A Novel Approach to Make Low-Fouling Polymeric Membranes

污垢现象在包括热交换、器官植入、心血管装置、牙齿和膜在内的广泛系统的性能中起着重要作用。在膜以外的区域，似乎大多数不粘附、不污染的表面都是相当疏水的，其临界表面张力小于30dynkm。然而，在膜工业中，在制造低污染膜时采用了相反的方法。生产出具有大于40 dykm临界表面张力的亲水性、高能表面膜。通过在膜中加入极性和甚至带电的官能团。这样做的一个动机是低表面能的膜很难湿润。除此之外，还有一些其他可能的原因，为什么不同的方法是不同的问题仍然存在。在提出的工作中，将使用一种新的接枝技术生产低表面能和高表面能膜。将对膜进行污垢试验和与各种污垢的性能试验，以确定其效果，研究可以导致新的膜材料。其他减少膜系统污染的方法，以及生产低污染膜的成本效益方法。

The phenomenon of fouling plays a major role in the performance of a wide range of systems including heat exchanges, organ implants, cardiovascular devices, teeth, and membranes. In areas other than the membranes, it appears that the most non-adhesive, non-fouling surfaces are quite hydrophobic, with critical surface tensions of less than 30dynkm. In the membrane industry, however, the opposite approach has been adopted in the making of low fouling membranes. Hydrophilic, high energy surface membranes are produced having critical surface tensions of greater than 40 dynkm. by incorporating polar and even charged functional groups in the membrane. One incentive for doing this is that membranes of low surface energy are difficult to wet. Beyond this and for a few other possible reasons, there remains the question of why the differ approach is different. In the proposed work, both low and high surface energy membranes will be produced using a novel grafting technique. The membranes will undergo fouling tests and performance tests with a variety of foulants to define the effect of the research can lead to new membrane materials, other approaches at minimizing fouling in membrane systems, and to a cost-effective means of producing low-fouling membranes.
