WS₂/nitrile butadiene rubber (NBR) nanocomposite was prepared by mechanical blending. The vulcanization and mechanical behavior, contact angle with water, friction and wear properties, as well as thermal stability were measured to investigate the influence of nano WS₂ content on the NBR. Moreover, scanning electron microscopic (SEM) and element dispersive spectrum analysis (EDS) were used to analyze the tensile failure mechanism of the WS₂/NBR nanocomposite. Results showed that the tensile strength, elongation at break and contact angle with water of the vulcanized rubber reached their maxima when the content of nano WS₂ was 10 parts. Furthermore, fast vulcanization rate and the minimum friction and wear properties were also observed. The tear strength, rebound resilience and electrical resistivity decreased with the increment of WS₂ content, while the hardness and thermal stability increased. Investigation on tensile fracture showed that crack growth was mainly caused by stress concentration.

通过机械共混制备了WS ₂ /丁腈橡胶（NBR）纳米复合材料。测量了硫化和机械性能，与水的接触角，摩擦和磨损性能以及热稳定性，以研究纳米WS ₂含量对NBR的影响。此外，使用扫描电子显微镜（SEM）和元素分散光谱分析（EDS）分析了WS ₂ / NBR纳米复合材料的拉伸破坏机理。结果表明，当纳米WS ₂含量增加时，硫化橡胶的拉伸强度，断裂伸长率和与水的接触角达到最大值。是10个零件。此外，还观察到快速硫化速率和最小的摩擦和磨损性能。随着WS ₂含量的增加，撕裂强度，回弹弹性和电阻率降低，而硬度和热稳定性增加。对拉伸断裂的研究表明，裂纹扩展主要是由应力集中引起的。
