제목 Interfacial Control of Transparent Nano Graphene Plates (nGP)/PVDF/nGP Composites Film as Acoustic Actuator
초록 Transparent thin film acoustic actuator and sensor have many other diverse applications. For instance, thin film speakers can work as transparent compact and lightweight general purpose flat panel loudspeakers. The high resonant frequency and required high driving electric field sill prohibit its use from most normal loudspeaker applications. Piezoelectric PVDF has been investigated to fabricate acoustic transducers. The developed nano graphene platelets based on transparent thin film acoustic transducer showed excellent acoustic response. Interfacial and electrical durability of nGP/PVDF/nGP composites were investigated for acoustic actuator applications. Improved interfacial adhesion of transparent nGP/PVDF/nGP film was contributed to increase the sound pressure level (SPL) as acoustic actuator.
