| 摘 要： | 采用机械混合方法制备碳纳米管／天然橡胶复合材料，随着碳纳米管添加量的增加，橡胶材料微观结构的均匀性下降，DSC曲线中结晶熔融峰面积逐渐减小，同时橡胶硫化返原现象减轻，硫化样品的交联度有所降低。碳纳米管在橡胶样品中显示出补强效应，碳纳米管复合材料的回弹、压缩疲劳性能明显优于炭黑补强样品，但其拉伸、撕裂性能水平较低。

| Abstract: | The natural rubber composites filled with carbon nanotubes (CNTs) were prepared by mechanical mixing. With the increasing of additive quantum of CNTs, the uniformity of microstructure in composites decreases, and the T_g slight rises. At the same time, the peak in DSC curve attributing to crystallization and melting weakens, and the gel fraction in cured rubber composites decreases. The reinforcing effect of CNTs is manifested in rubber composites, and the rebound degree, the dynamic compress properties of composites is superior. But the tensile and tear properties of rubber filled with CNTs are lower than that of samples filled with carbon black, the difference between them become greater with the increase in the content of reinforcing filler. |
