摘要
通过超声离心将酸化石墨烯和羟基化的多壁碳纳米管按照不同比例成功合成碳纳米管/石墨烯杂化材料。将杂化材料分散在环氧树脂体系中制备环氧树脂复合材料样条,研究杂化材料对环氧树脂力学性能的影响。通过扫描电镜(SEM)、透射电镜(TEM)和拉伸力学性能测试分析了杂化材料的分散性等微观结构以及环氧树脂复合材料的力学性能及断面形貌。碳纳米管/石墨烯杂化材料对环氧树脂有增强增韧的效果,其中石墨烯与碳纳米管之比为2∶1的杂化材料对环氧树脂的增强增韧效果最好。
The hybrid materials was made with the multi-carbon nanotubes（MWCNTs） and acidification graphene（f-GN） with different ratios by the process of ultrasonic and centrifugation.And the influence of hybrid materials to the epoxy resin（EP） composites which were made by adding hybrid materials into the system of EP was studied.The micromorphology and dispersity of hybrid materials were analyzed by scanning electron microscopy （SEM）and transmission （TEM）.The micromorphology of fracture surface of EP composites were characterized by the SEM and the tensile properties of EP composites also were tested.The results of tensile tests showed that the strengthening and toughening properties of EP could be improved by adding the hybrid materials,especially the while the ratio of MWCNTs ∶ f-GN was 2 ∶ 1 had the best enhancing and toughing effect to EP.
