Abstract:
In this article, we report on the exceptional application of polypyrrole/graphene composites (Ppy/G) for the corrosion protection of steel. Well-dispersed Ppy/G composites were successfully prepared using in situ solution polymerization. The prepared nanocomposites exhibited superior anticorrosion properties compared with the bare and epoxy, in which the corrosion protection efficiency increased 50–100 times with the Ppy(97)@G(3) pigment. The rheological and dielectric properties of the nanocomposites were superior to those of pure Ppy/epoxy. Ppy(97)@G(3) increased the thermal curing temperature from approximately 100°C to 110°C and considerably decreased the volume resistivity. The substantially improved properties of the nanocomposites were attributed to their high dispersions, which greatly enhanced the corrosion factors and barrier properties.
