This project aims to investigate the necessary polymer properties that would allow for dispersion of single-walled carbon nanotubes (SWNTs) within a castor-oil based polyol solvent, commercially sold as Setathane 1150. The use of this solvent is of interest to a customer of the company Inortech Chemie, located in Terrebonne, Quebec, as it is used in numerous coatings applications. To achieve the required dispersions, we will study the supramolecular interactions of commercial SWNTs with highly soluble derivatives of polythiophene, polyfluorene, and polycarbazole polymers that are specifically modified to impart solubility in alcohol-based solvents. We will also investigate the ability of the polymers to selectively interact with SWNTs of specific type, in an attempt to improve the purity of the dispersed materials. We will also determine the maximum concentration that can be dispersed in Setathane 1150 using these conjugated polymer derivatives. The studies will be carried out using thermogravimetric analysis, Raman, fluorescence, and absorption spectroscopy, as well as atomic force microscopy techniques.

该项目旨在研究必要的聚合物性质，使单壁碳纳米管（SWNT）分散在蓖麻油基多元醇溶剂中，商业上销售为Setathane 1150。 这种溶剂的使用是位于魁北克的特雷博讷的Inortech Chemie公司的客户感兴趣的，因为它用于许多涂料应用中。 为了实现所需的分散体，我们将研究商业单壁碳纳米管与聚噻吩，聚芴和聚咔唑聚合物的高度可溶性衍生物的超分子相互作用，这些聚合物被专门修改以赋予在醇基溶剂中的溶解性。我们还将研究聚合物选择性地与特定类型的单壁碳纳米管相互作用的能力，以提高分散材料的纯度。我们还将确定使用这些共轭聚合物衍生物可分散在Setathane 1150中的最大浓度。 这些研究将使用热重分析、拉曼、荧光和吸收光谱以及原子力显微镜技术进行。
