Abstract

In this study, the oxidative degradation of gamma-irradiated ultra-high-molecular-weight polyethylene (UHMWPE) was evaluated. Tensile yield stress, Young's modulus, and Vickers hardness were measured to characterize oxidative deterioration. Furthermore, we evaluated the existence of residual radicals by the electron spin resonance (ESR) analysis, and discussed the relationship between ESR spectra change and mechanical property indexes. In the tensile test of small UHMWPE specimens, it is often difficult to measure the strain. Therefore, we tried to estimate the Young's modulus simply by using Hertz's theory of elastic contact, and confirmed its usefulness. It is possible to estimate the tensile Young's modulus from the indentation test in this experimental range. This method is applicable to evaluate the relationship between mechanical properties such as Young's modulus and ESR properties over a long term after irradiation.

伽玛射线辐照下超高分子量聚乙烯氧化降解的研究
在这项研究中,研究了γ辐照的超高分子量聚乙烯(UHMWPE)的氧化降解。测量拉伸屈服应力、杨氏模量和维氏硬度来表征氧化变质。此外,我们通过电子自旋共振(ESR)分析来评估残余自由基的存在性,并讨论了ESR谱变化与力学性能指标之间的关系。在超高分子量聚乙烯(UHMWPE)小试件的拉伸试验中,应变的测量往往比较困难。因此,我们尝试简单地用赫兹的弹性接触理论来估计杨氏模量,并证实了它的实用性。在这个实验范围内,可以从压痕试验中估计拉伸杨氏模量。该方法适用于评估辐照后长期杨氏模量等力学性能与ESR性能之间的关系。
