摘要
以等离子体表面处理方式对多壁碳纳米管(简称碳纳米管)进行表面改性,采用红外光谱仪对原始碳纳米管和等离子体处理后的碳纳米管进行了表征,利用透射电镜观察了等离子体处理前后碳纳米管的形貌。以原始的碳纳米管和经过等离子体改性处理后的碳纳米管作为填料,制备了碳纳米管/环氧树脂复合材料,研究了等离子体处理前后碳纳米管的加入对环氧树脂的力学性能的影响。结果表明:添加碳纳米管后提高了环氧树脂复合材料的力学性能。原始碳纳米管质量分数达0.75%时,复合材料的拉伸强度、冲击强度分别较纯环氧树脂提高15.1%,4.8%。等离子体处理后的碳纳米管质量分数达1.00%时,复合材料的拉伸强度、冲击强度分别较纯环氧树脂提高77.0%,71.5%。并利用场发射电镜观察了碳纳米管在环氧树脂基体中的分散情况。
The multi-walled carbon nanotubes （MWCNTs） were modified by plasma surface treatment,the raw MWCNTs and plasma treatment MWCNTs were characterized by FTIR.The morphology of the raw MWCNTs and plasma treatment MWCNTs was observed by TEM.Raw MWCNTs and plasma treatment MWCNTs were used as fillers to prepare MWCNTs/epoxy resin composites.The effect of plasma treatment MWCNTs and raw MWCNTs on mechanical properties of epoxy resin was studied.The results indicate that the mechanical properties of the epoxy resin composites are enhanced with the addition of raw MWCNTs,and when the content of plasma treatment MWCNTs loading reaches 0.75%,the tensile strength,impact strength are higher 15.1%,14.8% than those of epoxy resin.When the content of the plasma treatment MWCNTs loading reaches 1.00%,the tensile strength,impact strength are increased by 77.0%,71.5% compared with those of epoxy resin.And the dispersion of the MWCNTs in the epoxy resin was observed by FE-SEM.
