摘要： Multi-layer coated materials and methods of making them are disclosed. In a specific embodiment, a porous polymeric substrate is pre-activated and immersed in a polyelectrolyte solution to form a first layer having an electric charge and at least one functional group. The coated material is next immersed in a second solution of a material having an electric charge opposite of that of the first layer to provide a bi-layer coating. This process can be repeated to form multi-layer coatings on porous substrates.

摘要翻译： 公开了多层涂覆材料及其制备方法。 在具体实施方案中，将多孔聚合物基材预活化并浸入聚电解质溶液中以形成具有电荷和至少一个官能团的第一层。 接着将涂覆的材料浸入具有与第一层相反的电荷的材料的第二溶液中以提供双层涂层。 可以重复该过程以在多孔基材上形成多层涂层。
