Method & Evidence

AimTo develop and demonstrate a scalable roll-to-roll manufacturing process for producing large-area, transparent, and flexible piezoelectric films suitable for loudspeaker applications.

MethodExperimental fabrication and characterization

ProcedureResearchers developed a novel roll-to-roll process to simultaneously align piezoelectric PZT nanoparticles and graphene nanoplatelets in a thickness-directional nanocolumn structure. This process was scaled up on a custom 44-ft-long R2R line to produce 6-inch-wide films.
