Butyl rubber/hydrophobized graphene oxide (HG) nanocomposites were prepared by solution mixing followed by compression molding process, and evaluated their properties using scanning electron microscope (SEM), oscillating disc rheometer (ODR), universal testing machine (UTM), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). The hydrophilic graphene oxide (GO) obtained through the oxidation of graphite (GP) was first hydrophobized with octadecylamine. The HG exhibit excellent dispersibility in toluene and stable under stationary condition for over 30 days. The chemical structure and functionality of HG was analyzed by fourier transform infrared (FTIR), raman spectroscopies, and wide-angle X-ray diffraction (WAXD) patterns. HG was successfully dispersed within BR matrix and result in significant reduction of curing time (around 30%), enhanced tensile strength (around 35%) as compared to the pristine butyl rubber. The air permeability of the hydrophobized graphene oxide composites was also significantly reduced by 75% compared to unfilled butyl rubber.

通过溶液混合和压缩成型工艺制备丁基橡胶/疏水化氧化石墨烯（HG）纳米复合材料，并使用扫描电子显微镜（SEM）、振动盘流变仪（ODR）、万能试验机（UTM）、热重分析（ TGA) 和差示扫描量热法 (DSC)。通过氧化石墨（GP）获得的亲水性氧化石墨烯（GO）首先用十八胺疏水化。HG 在甲苯中表现出优异的分散性，并且在静止条件下可稳定超过 30 天。通过傅里叶变换红外 (FTIR)、拉曼光谱和广角 X 射线衍射 (WAXD) 模式分析了 HG 的化学结构和功能。与原始丁基橡胶相比，HG 成功地分散在 BR 基体中，显着缩短了硫化时间（约 30%），提高了拉伸强度（约 35%）。与未填充的丁基橡胶相比，疏水化氧化石墨烯复合材料的透气性也显着降低了 75%。
