摘要

采用溶液混合法制备了石墨烯纳米片（GNP）/丁腈橡胶（NBR）纳米复合材料，并对其进行了有效的硫化。GNP悬浮液均匀分散在非常适合的NBR溶液中，最高可达2.4phr，并通过X射线衍射（XRD）进行表征。通过固化特性和溶胀试验，表征和研究了GNP对GNP/NBR纳米复合材料结构交联的影响。结果表明，与未填充的NBR相比，交联密度提高了42.3%，在1.2phr的GNP下溶胀率降低到19.7%。因此，对机械性能进行了研究，发现100%伸长率（M100）下的模量提高到约155%，硬度提高到约13%。这些结果通过使用扫描电子显微镜（SEM）的形态分析和在相同含量1.2phr的GNP下使用动态力学分析（DMA）将橡胶纳米复合材料中的储能模量作为温度的函数提高到约100%来验证。

Utilizing the Characteristics of Graphene Nano-Platelets to Improve the Cross-Linking Density of a Rubber Nano-Composite

Graphene nanoplatelets (GNP) / Acrylonitrile butadiene rubber (NBR) nanocomposites were prepared by solutions mixing method and vulcanized effectively. GNP suspension dispersed homogenously in a well-suited solution of NBR up to 2.4 phr and characterized by X-ray Diffraction (XRD). The influence of GNP on the cross-linking of GNP/NBR nanocomposites structure has been characterized and studied by the cure characteristics and swelling tests. The results showed that the cross-linking density was enhanced to 42.3% compared to that of unfilled NBR by reducing the swelling ratio to 19.7% at 1.2 phr of the GNP. Thus, the mechanical properties were investigated and revealed that the modulus at 100% elongation (M100) improved to about 155% and the hardness to about 13%. Those results were verified via the morphology analyzing using Scanning Electron Microscopy (SEM) and the enhancement of the storage modulus as a function of temperature in the rubber nanocomposite to about 100% utilizing Dynamic Mechanical Analysis (DMA) at the same content 1.2 phr of GNP.
