The recent advances in flexible piezoelectric technologies have sparked a great interest in developing multifunctional next‐generation transducers, which are in high demand for various challenging applications. Here, novel quasi 1–3 piezoelectric films with record‐high piezoelectric voltage coefficients (g33), reaching up to 0.709 Vm N−1, ≈20% greater than the recently reported highest g33 value in the literature, are reported. These composites are constructed via dielectrophoretic alignment of lead zirconate titanate (PZT) particles enhanced by graphene nanoplatelets, leading to densely structured cone‐shaped nanocolumn forests in the thickness direction. To demonstrate its potential applications, both structured and randomly dispersed samples are characterized and used in various applications ranging from energy harvesting to structural and personal health monitoring. Furthermore, when placed on the sensor surface, the oriented piezoelectric films are shown to detect even the slight movements of a small‐sized insect, demonstrating the ultrasensitivity of the system. Finally, to show the scalability of the dielectrophoretic process, a large area sample (12 ft long and 6‐in.‐wide) is also produced continuously via a novel multifunctional custom designed roll‐to‐roll manufacturing line. To the best of the knowledge, this is the largest single piece of piezoelectric film ever reported in the literature.

“…Interface optimizing has found widespread application in the fields of electric energy storage and light absorption of composites. − Especially for composites, optimizing the interface adhesion is significant for a different matrix of materials bonding into a whole composite. Cai et al indicated that Pb(Zr x Ti 1– x )O 3 (PZT) particle surface-treated by an organic agent could optimize the bonding interface with polyvinylidene fluoride (PVDF) polymer matrix. Specifically, composites with an optimized interface exhibited better flexibility and mechanical strength.…”

Presently, piezoelectric materials are gradually playing a significant role within composites to improve the damping and vibrational attenuation capacities of host composites. Previous studies paid attention to isolating the mechanical damping contribution and piezoelectric contribution of polymer-based piezoelectric composites (PPCs). However, reports detailing the piezoelectric damping of such materials have not paid sufficient attention to the technologies and methods to improve the piezoelectric damping of PPCs. In this study, we propose novel damping polyurethane (PU)-based piezoelectric composites with carbon-coated piezoelectric fillers (PZT@C/PU) with improved piezoelectric damping ability. The mechanical damping and piezoelectric damping of composites were theoretically decoupled, and we elaborate on the mechanism enhancing piezoelectric damping through the carbon coating strategy by comparing with the composites with nonpiezoelectric fillers. The as-fabricated core–shell structure having an optimized interface exhibits the proposed PZT@C/PU composite pads with relatively prominent damping ability (loss factor tan δmax = 1.0, tan δRT = 0.3), ductility (400.63%), and sound isolating behavior (transmission loss TL > 23 dB). Moreover, the vibration test results of as-fabricated sandwich structural PZT@C/PU composite damping devices exhibit outstanding vibration attenuating behavior (damping ratio ζ = 0.198). The study herein validates that the carbon shell coated on piezoelectric fillers would effectively increase damping performance of PU-based piezoelectric composites by the enhancement of piezoelectric performance caused by carbon coating piezoelectric fillers, which indicates that this material has potential for future applications in the field of vibration and noise reduction, thereby driving forward and expanding the fundamental understanding in the area of PPCs damping and vibration attenuation.
