Damage Mechanism of PET Irradiated by 25 MeV/u Kr Ions

  • 摘要: 通过25 MeV/u 86 Kr离子辐照叠层结晶聚对苯二甲酸乙二醇酯膜(PET), 在不同的电子能损(3.40-7.25 keV/nm)和离子注量(5×1011----3×1012 ions/cm2)辐照条件下, 对Kr离子在PET中引起的辐照损伤效应进行了研究。借助傅里叶变换红外光谱分析,通过对样品的红外吸收峰进行扣除基底后的Lorentz拟合,分析了与主要官能团对应的吸收峰强度的变化趋势, 研究了化学结构与组分在重离子辐照下的变化规律; 利用X射线衍射光谱仪测量, 研究了Kr离子在PET潜径迹中引起的非晶化过程,并通过对吸光度和非晶化强度随离子注量的指数衰减规律的分析, 获得了不同电子能损离子辐照PET时主要官能团的损伤截面和非晶化截面及对应的潜径迹半径。
    At room temperature, polyethylene terephthalate(PET) foil stacks were irradiated by 25 MeV/u Kr ions in the electronic stopping power range(3.3--7.66 keV/nm) and the fluence range from 5×1011 to 3×1012 ions/cm2. The behaviour of the main function groups with fluence and electronic stopping power were studied by using Fouriertransforminfrared(FTIR) spectroscopy, the degradation of the function group was investigated with the Lorentz fitting subtracted baseline. The amorphous processes in the latent tracks of PET were studied by Xray diffraction(XRD) measurements. The Kr ion induced degradation crosssection and amorphisation crosssections(radii) for different electronic energy loss were acquired from the experimental data(FTIR and XRD) by exponential decay function respectively. 
