利用光学吸收光谱、电子显微镜和拉曼光谱对半共轭有机聚合物和单壁纳米管的杂化体系进行了表征。结果表明，聚合物溶液能够使纳米管无限悬浮，而伴随的大部分非晶石墨析出溶液。电子显微镜和拉曼散射表明，通过插层过程，纳米管的绳索被破坏，导致单个纳米管很好地分散在聚合物基体中。此外，拉曼和吸收研究表明，聚合物优先与特定直径或直径范围内的纳米管相互作用。
Hybrid systems of a semiconjugated organic polymer and single-wall nanotubes have been characterized by optical absorption spectroscopy, electron microscopy, and Raman spectroscopy. It is demonstrated that solutions of the polymer are capable of suspending nanotubes indefinitely while the majority of the accompanying amorphous graphite precipitates out of solution. Electron microscopy and Raman scattering indicate that through an intercalation process, the ropes of nanotubes an destroyed, resulting in individual nanotubes being well dispersed within the polymer matrix. Moreover, Raman and absorption studies suggest that the polymer interacts preferentially with nanotubes of specific diameters or a range of diameters.
