Improvement of Electrical Conductivity of Polyurethane/Polypyrrole Blends by Graphene

Abstract:

Polyurethane (TPU)/polypyrrole (PPy) blends were successfully prepared by the solution blending process with different contents of reduce graphene oxide (rGO). The controlled synthesis of PPy/rGO composites was reported by varying graphene contents of 10, 20, 30 and 40% w/v. Fourier transform infrared (FTIR) and Scanning electron microscope (SEM) were used to characterize their structures and morphologies. The SEM images show the growing of PPy along the surface of graphene. FTIR illustrated that the PPy/rGO composites were in the doped state. The electrical conductivity of PPy/rGO composites with the concentration of graphene at 40% was about 30 times higher than that of pure PPy. Thermogravimetric analyzer (TGA) thermograms indicated that the PPy/rGO composites have better thermal stability than pure PPy.
