By the etching of PVDF (polyvinylidene) foils perpendicularly bombarded to their surfaces in advance with heavy ions at UNILAC (GSI Darmstadt, Germany), PVDF track microfilters are successfully manufactured and mostly evaluated by means of an optical microscope. The recipes of the elaboration, the properties as well as etching and technical parameters of the microfilters are summarized. The possible applications are also discussed briefly.
