The study investigates the tensile, flexural and thermal properties of epoxy resin matrix reinforced with pristine as well as amino-functionalized multi-walled carbon nanotubes (MWCNTs, 0, 0.25 and 0.50 wt%). The combination of ultrasonication and magnetic stirring has been used for the fabrication of MWCNTs/epoxy composite samples. The epoxy composite reinforced with 0.50 wt% amino-functionalized MWCNTs exhibits superior mechanical and thermal properties. The tensile and flexural strengths of this composite are noticed to be higher by about 13.5 and 17%, respectively, as compared with the neat epoxy specimen. The improvement in properties offered by amino-functionalized MWCNTs/epoxy composites is attributed to uniform distribution of MWCNTs in epoxy matrix as well as better interfacial adhesion between MWCNTs reinforcement and epoxy matrix, when compared with those noticed for epoxy composite reinforced with pristine MWCNTs.

多壁碳纳米管氨基官能化对多壁碳纳米管/环氧树脂复合材料力学和热性能的影响

该研究调查了用原始和氨基官能化的多壁碳纳米管（MWCNT，0、0.25 和 0.50 wt%）增强的环氧树脂基体的拉伸、弯曲和热性能。超声波处理和磁力搅拌的组合已被用于制造多壁碳纳米管/环氧树脂复合材料样品。用 0.50 wt% 氨基官能化多壁碳纳米管增强的环氧树脂复合材料表现出优异的机械和热性能。与纯环氧树脂样品相比，该复合材料的拉伸强度和弯曲强度分别高出约 13.5% 和 17%。氨基官能化多壁碳纳米管/环氧树脂复合材料性能的改善归因于多壁碳纳米管在环氧树脂基体中的均匀分布以及多壁碳纳米管增强材料与环氧树脂基体之间更好的界面粘合，
