摘要
实验研究了二甲基甲酰胺溶液敏化剂对PET材料中核径迹蚀刻特性改变的规律,描述了实验中观察到的新现象,并初步分析了敏化作用机理。
The dimethyl formamide （DMF） treatment effect in PET irradiated with 142 MeV 32^S was investigated. It is found that the change of track etching rate with changing the time and temperature of DMF treatment, with changing the time dipping in water before etching and changing the time stored in air after DMF treatment. New phenomenon observed in polymer dipped in water for more than 10 min between DMF treatment and etching process is also described in the paper.
