摘要：

Hydrothermal method was used to convert graphene oxide to graphene in water. Polyvinylpyrrolidone was added to improve dispersion of graphene and form a stable graphene solution with a high concentration. This stable graphene solution was used to mix with waterborne polyurethane (WPU) to prepare WPU/graphene composites. The electrical conductivity of WPU was greatly improved with incorporation of graphene, and when the filling amount of graphene is 4.0wt%, the conductivity of the composite reaches 8.30 x 10(-4) S cm(-1), which is a little higher than that of the composite prepared by in situ method.
