Abstract

This paper aims to investigate the ionizing radiation resistance of Butadiene (BR) and Vinyl-Silicone (VMQ) rubbers, which are the most promising candidates for Mars applications due to their low-temperature elasticity. The influence of various fillers on BR and aromatic silicone oligomer on VMQ radiation resistance was investigated by β or γ irradiation. The irradiation was carried out at two doses of 5 kGy or 10 kGy. In general, VMQ exhibits good radiation resistance even without the addition of the aromatic silicone oligomer. In contrast, the radiation resistance of BR was improved after the incorporation of the fillers, especially of mineral origin – silica, TiO2, or ZnO, which is probably a result of radiation interaction with the fillers’ particles instead of rubber macromolecules. Both rubbers have proved to be promising elastomer bases for designing future Mars rubber compounds.

火星用丁二烯和硅橡胶的抗电离辐射性能

丁二烯橡胶（BR）和乙烯基硅橡胶（VMQ）具有低温弹性，是最有希望在火星上应用的材料。采用β或γ辐照研究了不同填料对BR和芳香族有机硅低聚物抗VMQ辐射性能的影响。辐照剂量分别为5千戈瑞和10千戈瑞。一般情况下，即使不添加芳香族有机硅低聚物，VMQ也具有良好的耐辐射性能。相比之下，掺入填料后，BR的耐辐射性能得到了提高，尤其是矿物来源的二氧化硅、TiO2或ZnO，这可能是与填料颗粒而不是橡胶大分子的辐射相互作用的结果。这两种橡胶都被证明是设计未来火星橡胶化合物的有前途的弹性体基础。

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
