Abstract
The present invention relates to a method of producing a filter material and to a filter material produced by the described method. The method comprises the steps of providing a substrate and forming an electrically conductive structure on the substrate. Electrical insulating, fiber-like flock rods are then anchored to the substrate. A metal layer is then formed over the substrate and around the flock rods by electrodepositing. The substrate is separated from the electrodeposited metal layer and the flock rods are removed from the electrodeposited metal layer to produce a metal filter with microapertures traversing the thickness of the filter.
