“…They have also been applied in other polymer matrices for piezoelectric energy harvesting applications [ 35 ]. However, MOFs, either in 3D or in 2D morphology, have been comparatively less explored as fillers in PVDF matrices for different real-life applications [ 36 , 37 , 38 , 39 ]. They are a very emerging class of materials in present days for their environmental, catalytic, sensing, and biomedical applications and usability in the field of renewable energy [ 36 ].…”

These properties can further be coupled with the electroactive performances of PVDF, which is out of the scope of the present work.…”

“…Here we mainly focus on investigating the energy storage and mechanical energy harvesting performance of PVDF tuned by 2D MOF nanofiller addition. Owing to their porous structure and organic bonds, MOFs possess better compatibility with the PVDF matrix compared to that inorganic fillers [ 36 , 40 ]. Moreover, when the metal site of MOF is selected as the transition metals such as Mn, Fe, Co, Ni, etc., spontaneous polarization occurs between organic bonds and metal sites, which in turn forms unique nanoelectric domains, thereby improving the ferroelectric properties [ 40 , 41 ].…”

Here, we introduce a 2D metal-organic framework (MOF) into the poly(vinylidene fluoride) (PVDF) matrix, which has been comparatively less explored in this field. Highly 2D Ni-MOF has been synthesized in this regard via hydrothermal route and has been incorporated into PVDF matrix via solvent casting technique with ultralow filler (0.5 wt%) loading. The polar phase percentage of 0.5 wt% Ni-MOF loaded PVDF film (NPVDF) has been found to be increased to ~85% from a value of ~55% for neat PVDF. The ultralow filler loading has inhibited the easy breakdown path along with increased dielectric permittivity and hence has enhanced the energy storage performance. On the other hand, significantly enriched polarity and Young’s Modulus has helped in improving its mechanical energy harvesting performance, thereby enhancing the human motion interactive sensing activities. The piezoelectric and piezo-tribo hybrid devices made up of NPVDF film have shown improved output power density of ~3.26 and 31 μW/cm2 compared to those of the piezoelectric and piezo-tribo hybrid devices comprising of neat PVDF (output power density ~0.6 and 17 μW/cm2, respectively). The developed composite can thus be considered an excellent candidate for multifunctional applications.
