Abstract: A method for making a multilayer filter and the multilayer filter made by the method. The method includes steps of: coating a layer of nanofibers on a single side or both sides of a substrate medium to obtain a composite filter medium; and folding the composite filter medium in a serpentine arrangement to form the multilayer filter. Alternatively, the method includes steps of: coating a layer of nanofibers on both sides of a substrate medium to obtain a composite filter medium; and stacking up a plurality of sheets of the composite filter medium to form a multilayer filter. The multilayer filter comprises a top layer, a bottom layer and at least one unit between the top layer and the bottom layer. Each unit comprises two layers of nanofibers sandwiched between two layers of the substrate medium.
制造多层过滤器的方法和由所述方法制得的过多层过滤器。所述方法主要包括两个步骤。第一步骤是将纳米纤维层涂布在基体介质的一侧或两侧上以获得复合过滤器介质,第二步骤是以曲折方式折叠所述复合过滤器介质以形成多层过滤器。可选的是,所述第二步骤可以通过堆叠所述复合过滤器介质的若干片材以形成具有两层纳米纤维的结构的多层过滤器,所述两层纳米纤维夹在两层所述基体介质之间。由任一所述方法制造得到的多层过滤器含有至少一个结构单元,所述结构单元具有两层夹在两层基体介质之间的纳米纤维。
