Poly(3-hexylthiophene) (P3HT) supramolecular structures are fabricated on P3HT-dispersed reduced graphene oxide (RGO) monolayers and surfactant-free RGO monolayers. P3HT is able to disperse RGO in hot anisole/N,N-dimethylformamide solvents, and forms nanowires on RGO surfaces through a RGO induced crystallization process. The TEM and AFM investigation of the resultant P3HT/RGO composites shows that P3HT nanowires grow from RGO, and connect individual RGO monolayers. Raman spectroscopy confirms the interaction between P3HT and RGO, which allows the manipulation of the RGO electrical properties. Such a bottom-up approach provides interesting graphene-based composites for nanometer-scale electronics.
聚（3-己基噻吩）（P3HT）超分子结构是在P3HT分散的还原氧化石墨烯（RGO）单层和无表面活性剂的RGO单层上制备的。P3HT能够在热的茴香醚/N，N-二甲基甲酰胺溶剂中分散RGO，并通过RGO诱导的结晶过程在RGO表面形成纳米线。对所得P3HT/RGO复合材料的TEM和AFM研究表明，P3HT纳米线从RGO生长，并连接各个RGO单层。拉曼光谱证实了P3HT与RGO之间的相互作用，这使得能够操纵RGO的电学性质。这种自下而上的方法为纳米级电子学提供了有趣的基于石墨烯的复合材料。
