摘要:
采用Materials Studio分子模拟软件建立了具有不同手性指数和直径的碳纳米管(CNT)/丁腈橡胶(NBR)复合材料的分子模型,同时采用恒应变法对CNT/NBR复合材料的力学性能进行了计算,并研究了CNT的手性指数和直径对CNT/NBR复合材料力学性能的影响。结果表明,相比于扶手椅型CNT和锯齿型CNT,螺旋型CNT对CNT/NBR复合材料力学性能的增强效果最好;随着CNT直径的增加,CNT对CNT/NBR复合材料力学性能的增强效果不断减弱。
Abstract:
Molecular models of nitrile rubber (NBR) composites reinforced by carbon nanotube (CNT) (CNT/NBR composites) with different chirality and diameter were developed using the Materials Studio software, the mechanical properties of CNT/NBR composites were calculated via the constant strain method, and the effects of chirality and diameter of CNT on the mechanical properties of CNT/NBR composites were studied.The results indicated that compared with the armchair CNT and the zigzag CNT, the spiral CNT had the best reinforcement effect on the mechanical properties of CNT/NBR composites.The reinforcement effect of CNT on the mechanical properties of CNT/NBR composites was weakened with the increase of CNT diameter.
