Polyrhtiophene Lab Report

Polyhtiophene/graphene oxide nanocomposite (PTh/GO NC) was prepared by first dispersing 0.4 g of GO nanosheets in 30 mL of chloroform in a conical flask under sonication for 30 minutes. Thereafter, 0.95 mL of thiophene monomer was injected into the reaction mixture while stirring magnetically for further 30 minutes. To this mixture, FeCl3 (8 g) was poured in one go and left for 6 h under stirring at room temperature. Thereafter, the obtained suspension was vacuum filtered and repeatedly rinsed with deionised water and methanol, until the pH of the colourless filtrate was 7. Finally, the solid materials (PTh/GO NC) were vacuum dried at 60oC for 24 h. The total mass of NC was 1.4 g, and the compositions of GO and PTh were 28.5 wt.% and 71.5
