摘要/Abstract

摘要： 本文先采用混酸对多壁碳纳米管(MWCNTs) 和石墨烯微片进行氧化处理,再通过超声作用制备了碳纳米管/石墨烯杂化材料,使碳纳米管通过π-π 作用与酸化石墨烯结合在一起。在此基础上,将制得的杂化材料分散在环氧树脂体系中制成样条,研究其力学性能的变化。通过红外光谱(FT-IR) 分析表明成功制取了酸化碳纳米管、酸化石墨烯及其相应的杂化材料。通过透射电镜(TEM) 直观地展示了酸化后MWCNTs、石墨烯的形态变化和杂化材料的形态; 对样条进行力学性能测试并用扫描电镜(SEM) 观察其断面形态。结果表明,环氧树脂中加入杂化材料能有效增加环氧树脂的韧性和强度,且经过超声作用制得的杂化材料和选用酸化碳管的杂化材料的增强增韧效果更好,加入酸化超声作用混合杂化材料的增强增韧效果最明显。

Abstract: The multi-walled carbon nanotubes (MWCNTs) and grapheme nanoplatelets were oxidized by the vitriol/nitric acid,and then the carbon nanotubes/graphene hybrid materials were prepared through the ultrasonic function method by the π-stacking interactions between the MWCNTs and graphene. Finally,we dispersed the carbon nanotubes/graphene hybrid materials into epoxy resin system to study the effect of the hybrid materials on the tensile properties of epoxy composites. The FTIR experimental results indicated that the hybrid materials were prepared and the acidification on the carbon nanotubes and graphene were successful resulting increasing the functional groups. The results of tensile tests showed that the addition of carbon nanotubes/graphene hybrid materials in epoxy resin can effectively increase the toughness and strength of the epoxy resin. Moreover,the tensile strength and toughness of the epoxy resin composites were gradually increased by the addition of the carbon nanotubes/graphene hybrid materials.

Key words: carbon nanotubes, graphene, hybrid materials, strengthening, toughening
