摘要
By introducing polyaniline nanofibers (PaniNFs) as a stabilizer during the conversion of graphene oxide to graphene in an aqueous medium under ultrasound, the aggregation of the intermediates and products was effectively suppressed. A stable dispersion of PaniNFs and graphene (G) with a high concentration was obtained. This method represents a convenient and potential route to prepare a PaniNF-G dispersion on a large scale, which may increase the applications of graphene. Vacuum filtration of the dispersion yields a high-quality self-supporting PaniNF/G composite film, whose electrical conductivity can be increased by rinsing with hydrochloric acid.
