摘要:

如何获得单一导电属性的单壁碳纳米管(SWCNT), 使其在各领域得到更广泛的应用, 引起了科研人员越来越多的关注. 琼脂糖凝胶电泳(AGE) 法以其简便, 低成本, 可规模化等优点在分离金属型(m-)和半导体型(s-)单壁碳纳米管的诸多分离方法中体现出独特的优势. 本文利用紫外-可见-近红外(UV-Vis-NIR) 吸收光谱分析手段, 系统研究了NaCl 的添加对AGE 法分离SWCNT 的影响. 研究发现NaCl 的添加对SWCNT 的分离有一定的影响: 当NaCl 添加量低于70 mmol·L^-1时, 可以提高分离后体系中s-SWCNT 的相对含量; 当NaCl 添加量高于70 mmol·L^-1时, 随着添加量的增加, NaCl 的加入开始抑制m-SWCNT 和s-SWCNT 的有效分离; 当NaCl 添加量达到160 mmol·L^-1时体系分离效率明显降低. 我们推测这种影响主要是由盐的添加改变了分散剂在m-SWCNT 和s-SWCNT 表面的吸附结构引起的.

Abstract:

Plenty of attention has been paid to obtaining single-walled carbon nanotubes (SWCNT) with single conductive properties so that they can be applied in various fields. Among the separation techniques used for metallic (m-) and semiconducting (s-) single-walled carbon nanotubes, agarose gel electrophoresis (AGE) is thought to be a relatively simple and low-cost method. In this work, we used UV-visible-near infrared (UV-Vis-NIR) absorption spectroscopy to study the effect of NaCl on the separation of SWCNT by AGE. Our results show that the addition of NaCl greatly influences the separation of the SWCNT. At a NaCl concentration of less than 70 mmol·L^-1, the relative content of s -SWCNT increased after separation and at a NaCl concentration of higher than 70 mmol·L^-1, the separation of m-SWCNT and s-SWCNT was restrained as the concentration of NaCl increased. At a NaCl concentration of 160 mmol·L^-1, the separating efficiency of the system dropped markedly. We suggest that the addition of NaCl may change the adsorption properties of the surfactant towards m-SWCNT and s-SWCNT.
