Thin-film of polyvinylidene fluoride (PVDF)–Zinc metal oxide frame work (Zn-MOF) with varying composition, i.e., (0, 4, 8, 12 wt.%), have been fabricated by a solution-casting route. X-ray diffraction and scanning electron microscopy (SEM) were used to investigate the PVDF -Zn MOF nanocomposite samples. XRD spectra demonstrate two-dimensional character of Zn-MOF. In polyvinylidene fluoride (PVDF), MOF fillers were added at 4, 8 and 12 wt.% nanocomposites film demonstrate a relatively high dielectric constant (εᶦ = 10.7) at 42 Hz frequency, and low loss at 106 Hz frequency. The dielectric constant is enhanced due to charge accumulation at the interfaces between different phases or materials within a heterogeneous structure (Maxwell-Wagner polarization). We have presented a new method of constructing PVDF-Zn-MOF nanocomposites with enhanced dielectric constant and thermal properties at the same time. With the addition of Zn-MOF and their increasing wt.%, DSC analyses confirmed that not significant structural changes when subjected to heat. This nanocomposite system of high dielectric constants is also desirable for embedded capacitors as it can improve frequency response and reduce impedance and inductance.
