摘要

采用电子顺磁共振和傅里叶红外光谱方法对辐照后的聚乙烯/CdS + ZnS (PE/CdS + ZnS)复合材料进行了研究。基于电子顺磁共振谱，确定了诱发顺磁辐射缺陷的性质及其与γ辐射吸收剂量的定量关系。在吸收剂量D γ = 30-100 kGy范围内，与纯聚合物相比，所研究的聚合物复合材料具有更高的抗辐射能力。傅里叶红外光谱证实了这一结果，并表明这种变化与γ量子辐照PE/CdS + ZnS的超分子结构变化有关

Spectral Investigations of γ-Irradiated Polyethylene/CdS+ZnS Composite Films

Gamma-irradiated samples of the polyethylene/CdS + ZnS (PE/CdS + ZnS) composite were studied by electron paramagnet resonance and Fourier infrared spectroscopy methods. Based on the electron para-magnet resonance spectra, the nature of the induced paramagnetic radiation defects and their quantitative dependence on the absorbed dose of gamma radiation are identiﬁed. It has been established that the studied polymer composites have a higher radiation resistance in the range of absorption doses D γ = 30–100 kGy compared to pure polymer. The obtained results were conﬁrmed by Fourier infrared spectroscopy, and it was shown that the observed changes are associated with a change in the supramolecular structure of PE/CdS + ZnS irradiated with γ -quanta
