The preparations of fluorographene nanosheets and research in tribological properties in high vacuum

In this study, fluorographene nanosheets (FG nanosheets) were prepared via the solventultrasonic exfoliation method. The fluorographene sheets were observed using field-emission scanning electron microscopy (FE-SEM). The microstructure of the as-prepared FG nanosheets was characterized by X-ray diff...
