To achieve efficient thin film fabrication, the single step fabrication of conjugated polymer thin film have been required due to complex steps of thin film fabrication with self-assembly inducement of conjugated polymer and thin film fabrication process. Here, we introduce solution-floating method for thin film of poly(3-hexyl thiophene) (P3HT) nanowires (NWs). Well-dissolved P3HT chains are self-assembled into one-dimensional P3HT NWs, and these NWs then form a thin film during the evaporation of the floated organic solvent. Systematic TEM experiment presents for the first time the unique self-assembly mechanism behind the formation of P3HT NWs from the self-assembly of P3HT micelles. Also, nanomorphologies of thin film formed by solution-floating method are affected by the properties of good solvent. These generated thin films on water can be easily transferred onto a Si wafer for organic field-effect transistor (OFET) device and excellent carrier mobility of 0.012 cm2/V∙s. |
