摘要
采用混合晶红外光谱、X-射线衍射及小角散射、差示扫描量热法研究γ-射线辐照对溶液生长聚乙烯单晶的影响,表明γ-射线辐照在单晶的规则折叠区也引起了不可忽视的结构缺陷或畸变。
The effects of γ-ray irradiation on the structure of the solution-grown polyethylene single crystals were studied by means of the infrared spectroscopy , X-ray wide angle diffraction and small angle scattering as well as differential scanning calorimetry on the mixed crystals of polyethylene and deuterated polyethylene. The results showed that appreciable structural defects and distortions were caused by the γ-ray irradiation in the ordered regions consisting of regularly folded crystalline stems.
