多壁碳纳米管的表面修饰及分散性
|
摘要
为提高多壁碳纳米管的分散性,以扩大在多领域的应用效果,用不同比例混酸氧化处理原始多碳纳米管,分别运用γ-氨丙基三乙氧基硅烷、γ-(2,3-环氧丙氧基)丙基三甲氧基硅烷、γ-(甲基丙烯酰氧)丙基三甲氧基硅烷三种硅烷偶联剂继续修饰混酸改性的多壁碳纳米管,利用红外光谱仪、X射线衍射仪对其进行表征,在五种不同极性溶剂中进行了分散性实验。结果表明,体积比3∶1的混酸对MWNTs的处理效果最好。该结果为碳纳米管的在诸多领域的实际应用提供一定的借鉴和参考。
This paper attempts to improve the dispersibility of multi-walled carbon nanotubes and enhance its application effects in various fields. The targeted research includes acid-oxidizing the original multi-carbon nanotubes using different ratios of mixed acid; modifying the acid-oxidized multi-carbon nanotubes by the silane coupling agents,such as ethoxysilane,γ-( 2,3-epoxypropoxy) propyltrimethoxysilane and γ-( methacryloxy) propyltrimethoxysilane; characterizing them by infrared spectrometer and Xray diffractometer; and performing dispersion experiments on five different polar solvents. The results show that 3∶ 1 mixed acid has the best treatment effect on MWNTs. The result may provide a certain reference for the practical application of carbon nanotubes in many fields.
