Abstract

In this paper, graphene oxide (GO) and carbon nanotube (CNT) hybrid fillers were used to replace partial carbon black (CB), and GO/CNT/CB/NR composites were prepared with excellent crack growth resistance, low heat build-up and superior mechanical properties. Mechanical testing revealed a significant synergistic reinforcement between GO/CNT and CB in NR composites. The improved dispersion of GO/CNT hybrid fillers and CB in the NR matrix was characterized by transmission electron microscopy (TEM). Through the fatigue test, the GO/CNT/CB/NR composites showed excellent fatigue crack growth resistance and low heat build-up compared to CB/NR composites. These properties provide the NR composites with better applications in industry.

摘要

在本文中，氧化石墨烯（GO）和碳纳米管（CNT）混合填料被用于替代部分炭黑（CB），并制备了具有优异抗裂纹扩展性能、低生热和卓越力学性能的GO/CNT/CB/NR复合材料。力学测试表明，在天然橡胶（NR）复合材料中，GO/CNT与CB之间存在显著的协同增强作用。通过透射电子显微镜（TEM）对GO/CNT混合填料和CB在NR基体中改善的分散情况进行了表征。通过疲劳试验，与CB/NR复合材料相比，GO/CNT/CB/NR复合材料表现出优异的抗疲劳裂纹扩展性能和低生热性能。这些性能使NR复合材料在工业中具有更好的应用。
