| 摘 要： | 探讨了蚀刻剂中重铬酸钾浓度、硫酸浓度及蚀刻温度、蚀刻时间等因素对聚丙烯膜基体蚀刻速率的影响；建立了基体蚀刻速率与重铬酸钾浓度，硫酸浓度、蚀刻温度的数学关联式；并选择一定的蚀刻条件对辐照过的聚丙烯膜进行蚀刻，得到了预期孔径的聚丙烯核孔膜。

| Abstract: | The chemical etching techniques of polypropylene (PP) nuclear track membrane were studied. The effects of potassium dichromate concentration, sulfuric acid concentration, etching temperature and etching time on the bulk etching rate of PP nuclear track membrane were discussed. A mathematical relation has been established. Under certain etching conditions, the expected PP nuclear track membranes were made by etching the irradiated PP membrane, affirming the mathematical relation. |
