This paper comprehensively reviews the research on PVDF-based piezoelectric nanocomposites prepared by 3D printing technology and discusses methods such as structural design to improve their energy harvesting and storage performance.
Recently, polyvinylidene fluoride (PVDF) based nanocomposites have attracted much attention for next-generation wearable applications such as promising piezoelectric energy harvesters (nanogenerators), energy storage devices, sensing devices, and biomedical devices due to their high flexibility, and high dielectric and piezoelectric properties. 3D printing technology, PVDF based piezoelectric nanocomposites, the studies based on 3D printing of PVDF based piezoelectric nanocomposites by inkjet printing and fused deposition modeling, and enhancements of energy harvesting and storage performance of nanocomposites by structural design are comprehensively overviewed here. An insight is provided into 3D printing techniques, structure and properties of PVDF based polymers, various nanofillers and production methods for nanocomposites, solutions to enhance beta phase (crystallinity) of PVDF, and improvements of nanocomposites' breakdown strength, discharged energy density, and piezoelectric power output by mentoring structural design.
