COATED ASYMMETRIC MEMBRANE SYSTEM HAVING OLEOPHOBIC AND HYDROPHILIC PROPERTIES
摘要：
A porous membrane assembly includes, in an exemplary embodiment, a porous membrane substrate having hydrophobic properties. The membrane substrate includes a first side, an opposing second side and a plurality of pores extending therethrough. The membrane substrate also includes a discontinuous layer of an oleophobic coating applied to the first side so that the plurality of pores in the first side are substantially free of the oleophobic coating, and a continuous layer of an amine containing hydrophilic polymer coating applied to the second side of the membrane substrate.
摘要（中）：

在一个示例性实施方案中，多孔膜组件包括具有疏水性质的多孔膜基材。 膜基板包括第一侧，相对的第二侧和从其延伸的多个孔。 膜基底还包括涂覆在第一侧的疏油涂层的不连续层，使得第一侧中的多个孔基本上不含疏油涂层，并且将连续的含有亲水性聚合物涂层的胺层施加到第二侧 侧膜。
