Abstract By incorporating carbon nanotubes (CNTs) and graphene nanomaterials with aromatic sp2 carbon structures, we have specifically tuned filled ethylene propylene diene monomer elastomer (EPDM) seal and gasket composite materials for radiation resistance. Our results show that CNTs and graphene have an increased ability to stabilize the EPDM matrix compared to standard carbon black (CB) as a radiation-resistant filler. Graphene outperforms both CNT and CB fillers when considering surface damage under conditions where beta exposure is an issue. Both graphene and CNT fillers offer significantly reduced changes in glass transition temperature under prolonged exposure to tritium compared to CB-filled standards, with a 2.5-fold and almost 5-fold reduction, respectively. Thus, CNT- and graphene-filled O-ring materials could be designed that would maintain acceptable seals significantly longer than currently used composites.

氚对芳香碳载聚合物的影响

摘要 通过结合碳纳米管 (CNT) 和具有芳香 sp2 碳结构的石墨烯纳米材料，我们专门调整了填充的三元乙丙橡胶 (EPDM) 密封和垫片复合材料的耐辐射性。我们的结果表明，与作为抗辐射填料的标准炭黑 (CB) 相比，碳纳米管和石墨烯具有更高的稳定 EPDM 基质的能力。在考虑β暴露问题的条件下的表面损伤时，石墨烯的性能优于碳纳米管和碳纤维填料。与 CB 填充标准相比，石墨烯和 CNT 填充物在长时间暴露于氚的情况下都显着降低了玻璃化转变温度的变化，分别降低了 2.5 倍和近 5 倍。因此，
