碳纳米管吸附有机物研究进展

Research Progress in Adsorption of Organic Chemicals on Carbon Nanotubes

碳纳米管由于其独特的性质和广泛的应用前景,在作为吸附材料方面已引起国内外研究者的广泛兴趣.目前有关碳纳米管对有机物的吸附机理主要集中在以下几种作用:疏水作用、π-π键作用、H键作用、静电作用力等.由于碳纳米管在吸附有机物时,以上几种作用力可能同时存在,因而很难仅通过一种机理来预测碳纳米管对某有机物的吸附作用.不同类别的物质的吸附作用,起主导作用的吸附机理不同.因此,要预测有机物与碳纳米管之间的相互作用力,需要建立不同的吸附模型.另外,研究碳纳米管与有机物的吸附作用,在研究碳纳米管性质、有机物性质的同时,作用环境的研究也显得非常重要.

The carbon nanotubes （CNTs） have drawn special research attention because of their unique properties and potential applications. Because the different mechanisms may act simultaneously, mainly hydrophobic interactions, π-π bonds, electrostatic interactions, and hydrogen bonds, the prediction of organic chemical adsorption on CNTs is not straightforward. The dominant adsorption mechanism is different for different types of organic chemicals （such as polar and nonpolar）, thus different models may be needed to predict organic chemical-CNT interaction. Adsorption mechanisms will be better under stood by investigating the effects of properties of both CNTs and organic chemicals along with environmental conditions.
