Production, Properties and Applications of Nuclear Track Microfilters

摘要: 核微孔过滤器是利用重离子辐照高分子材料后经化学蚀刻而制成的新型过滤介质，它具有真实的孔径和高选择过滤性能．本文讨论了核微孔过滤器的生产原理、方法、特性和应用． 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.
