Production, Properties and Applications of Nuclear Track Microfilters

Key words: 
• heavy ion irradiation /
• chemical etching /
• pore size /
• selectivity and threshold of microparticle retention

Abstract: The nuclear track microfilter has a true pore size and high selectivity,which are produced by irradiating a variety of polymers such as PC, PET, Kapton and PVDF using heavy ions and subsequent etching with the appropriate etchant. The pore size and porosity of the nuclear trackmicrofilters can be preselected according to what is required, their properties as well as already tested or possible applications are discussed.
