Abstract Hybrid fillers are making a remarkable improvement in the properties of polymeric systems. In the present study, the influence of hybrid of multiwalled carbon nanotube (MWCNT) and nanoclay on the mechanical, electrical and transport properties of nitrile rubber (NBR)/natural rubber (NR) blends has been investigated. Attempts were made to prepare NBR/NR/CNT/nanoclay composites on a two-roll mill and to study various mechanical properties such as tensile strength, tear resistance, abrasion loss and compression set percent. Transport, thermal and electrical properties were also investigated. By virtue of the synergism between MWCNT and nanoclay, the composites exhibited enhancement in the mechanical properties by the immobilization of rubber chains via coupling action between the filler surface and the rubber molecules. The fine and uniform dispersion of both CNT and clay in composite samples supported the observation. The hybrid filler system had a great impact on the thermal and electrical properties of the composites. Graphical abstract

CNT/粘土混合物对 NBR/NR 混合物的机械、电气和传输性能的作用

摘要 混合填料正在显着改善聚合物体系的性能。在本研究中，研究了多壁碳纳米管 (MWCNT) 和纳米粘土的混合物对丁腈橡胶 (NBR)/天然橡胶 (NR) 共混物的机械、电气和传输性能的影响。尝试在两辊轧机上制备 NBR/NR/CNT/纳米粘土复合材料，并研究各种机械性能，如拉伸强度、抗撕裂性、磨损损失和压缩永久变形百分比。还研究了传输、热和电特性。由于多壁碳纳米管和纳米粘土之间的协同作用，通过填料表面和橡胶分子之间的耦合作用固定橡胶链，复合材料表现出机械性能的增强。碳纳米管和粘土在复合样品中的精细且均匀的分散支持了这一观察结果。混合填料体系对复合材料的热性能和电性能有很大影响。图形概要
