Carbon nanotube is one of the important topics of interest in the nanotechnology science. Many scientists have been interested in surface-modified nanotubes for decades. In this study, multi-walled carbon nanotubes (MWCNTs) were functionalized with polyethylene glycol and dithiols in esterification reactions. The MWNTs were first carboxylate-functionalized. The carboxylated MWCNTs were acyl chlorite substituted. The functionalized MWNTs were used as the precursor to esterification of polyethylene glycols and thiols. The reactions were performed catalysts or non-catalysts, solvent-free and solvent media, using microwave-assisted and classical methods. The synthesized compounds were characterized by FTIR, TGA, TEM and NMR techniques. We investigate the advantage of microwave synthesis method in terms of time and solvent in Green Chemistry. The obtained compounds exhibit very interesting results in their complexes with metals due to containing free hydroxyl and thiol groups.

巯基乙二醇官能化碳纳米管的合成及FTIR,TEM,TGA和NMR技术的表征

碳纳米管是纳米技术领域关注的重要主题之一。数十年来,许多科学家一直对表面改性的纳米管感兴趣。在这项研究中,多壁碳纳米管(MWCNTs)在酯化反应中被聚乙二醇和二硫醇官能化。MWNT首先被羧酸官能化。羧化的MWCNT被酰基亚氯酸酯取代。官能化的MWNT用作聚乙二醇和硫醇的酯化的前体。使用微波辅助和经典方法,在无溶剂和溶剂介质下,以催化剂或非催化剂进行反应。通过FTIR,TGA,TEM和NMR技术对合成的化合物进行表征。我们研究了绿色化学中微波合成方法在时间和溶剂方面的优势。
