Abstract

In the realm of polymer composites, the research of nanoparticles has risen in prominence. Graphene oxide (GO) is one of the best nanofillers in natural rubber (NR). In this work, GO nanosheets are utilized as reinforcement in an NR composite to anticipate mechanical characteristics. The researchers project the effect of GO sheets in NR with varied volume percentages and defective GO sheet reinforcement in NR composites. When the volume percentage of GO sheet in the NR nanocomposite is 4.6% and 7.2%, respectively, the value of Young's modulus rose by 68.8% and 166.2%. GO/NR with a 7.2% volume fraction has the highest ultimate tensile strength as compared with lower volume fractions of GO/NR nanocomposites. An increase of 63.49% in ultimate tensile strength in GO/NR nanocomposites (7.2% vol fraction) is seen as compared with pristine NR. Creep characteristics of NR nanocomposites are also investigated. The results reveal that the addition of GO sheets considerably increases the creep resistance strength of NR nanocomposites. The zone of secondary creep grows narrower as the continuous stress level increases.

氧化石墨烯增强天然橡胶复合材料力学性能和蠕变行为的原子模拟

在聚合物复合材料领域，纳米颗粒的研究日益突出。氧化石墨烯（GO）是天然橡胶中最好的纳米填料之一。在这项工作中，GO纳米片被用作NR复合材料中的增强材料，以预测机械特性。研究人员预测了不同体积百分比的GO片材在NR中的作用以及NR复合材料中有缺陷的GO片材增强。当GO片在NR纳米复合材料中的体积百分比分别为4.6%和7.2%时，其杨氏模量值分别提高了68.8%和166.2%。与体积分数较低的GO/NR纳米复合材料相比，体积分数为7.2%的GO/NR具有最高的极限拉伸强度。与原始NR相比，GO/NR纳米复合材料（体积分数为7.2%）的极限拉伸强度提高了63.49%。还研究了NR纳米复合材料的蠕变特性。结果表明，GO片的加入显著提高了NR纳米复合材料的抗蠕变强度。随着连续应力水平的增加，二次蠕变区变窄。
