摘要： The present invention provides a novel fibrous membrane comprising at least one substrate layer comprising at least 80% by weight of microfibers that carry positively charged and/or negatively charged functional groups, and at least one layer of filtration material attached to the substrate layer, wherein the layer of filtration material comprises at least 80% by weight of nanofibers that carry negatively charged and/or positively charged functional groups. The fibrous membrane is able to remove or reduce the concentration of bacteria, viruses and heavy metals while maintaining relatively high water flow. The invention also relates to filter comprising the fibrous membrane and a method for manufacturing the fibrous membrane.
