In this work, graphene/nature rubber (GE/NR) composites with filler content from 0 wt% to 1 wt% were prepared by an in situ reduction process. Thermal properties of the nanocomposites were studied by thermogravimetric (TG) analysis and thermogravimetric difference (ΔTG). Composites with higher GE content evidenced stronger thermal stability-enhancing effect. Kinetic analysis showed that the activation energies () during degradation of composites were always higher than pure NR. However, reached its maximum at 0.1 wt% GE content and started to decrease with further increase in GE loading. The changes in the thermal properties were attributed to the chemical structure and heat transfer properties of graphene sheets.

原位共混石墨烯/天然橡胶纳米复合材料的热性能研究

在这项工作中，通过原位还原工艺制备了填料含量为0 wt％至1 wt％的石墨烯/天然橡胶（GE / NR）复合材料。通过热重分析（TG）和热重差（ΔTG）研究了纳米复合材料的热性能。具有较高GE含量的复合材料表现出更强的热稳定性增强作用。动力学分析表明，复合材料降解过程中的活化能（）始终高于纯NR。然而，在GE含量为0.1 wt％时达到了最大值，并随着GE负载的进一步增加而开始下降。热性质的变化归因于石墨烯片的化学结构和传热性质。
