Abstract Protection against sulfur mustard (HD) is essential for the safety of the operators in the lab and in war. In this research, graphene oxide/butyl rubber (GO/IIR) composites were first prepared by a green method of latex compounding. This method achieved uniform dispersion of GO in IIR matrix for the GO content up to 2 phr (parts per hundreds of rubber). More importantly, there was a strong interfacial interaction between GO and IIR chains. When the GO content was 2 phr, the tear and tensile strengths of the GO/IIR composites were increased by 44% and 102%, respectively, compared with those of pure IIR. Additionally, it was found that the protective barrier properties against HD of GO/IIR composites increased with the increase in the GO content. When the GO content was 3 phr, a shielding filler network was formed by GO in the IIR matrix, and the diffusion coefficient of HD in IIR was decreased by 46%. The research results are of substantial importance for protection against HD and against more toxic gases or liquids.

氧化石墨烯/丁基橡胶复合材料对硫芥的高阻隔性能

摘要 防止硫芥 (HD) 对实验室和战争中操作员的安全至关重要。在这项研究中，氧化石墨烯/丁基橡胶 (GO/IIR) 复合材料首先通过乳胶复合的绿色方法制备。该方法实现了 GO 在 IIR 基质中的均匀分散，GO 含量高达 2 phr（每百份橡胶的份数）。更重要的是，GO 和 IIR 链之间存在很强的界面相互作用。当GO含量为2 phr时，与纯IIR相比，GO/IIR复合材料的撕裂强度和拉伸强度分别提高了44%和102%。此外，还发现 GO/IIR 复合材料对 HD 的保护屏障性能随着 GO 含量的增加而增加。当 GO 含量为 3 phr 时，IIR 基体中的 GO 形成了屏蔽填料网络，HD在IIR中的扩散系数降低了46%。研究结果对于预防 HD 和毒性更大的气体或液体具有重要意义。
