Flexible and transparent graphene films have been fabricated in large scale via inkjet printing and vapor deposition (VDP) method. Furthermore, the fabricated graphene thin film was used as an electrode of poly(vinylidene fluoride) (PVDF)-based acoustic actuator. To the best of our knowledge, this is the first attempt of utilizing graphene electrode as a transparent flat-panel speaker, which is derived from the vacuum-assisted reduction of graphene oxide (GO) film by inkjet printing. The prepared graphene-based acoustic actuator had much less power consumption compared to the commercial thin film speaker, and it was expected to be used as an extremely thin and lightweight loudspeaker. In addition, we also applied it for active noise cancellation (ANC) system. |
