Polyvinylidene fluoride (PVDF) based polymer nanocomposites with ceramics as nanofiller have been investigated a solution for energy storage devices due to their unique and attractive combination of processability electrical properties. This work assesses two dopants (fluorine nitrogen) zinc oxide (ZnO) nanoparticles PVDF matrix composites means improving dielectric properties targeting capacitive storage. Fluorine doping achieves improved performance compared pure ZnO increasing the decomposition temperature by 15 °C 463 wt% F-doped reducing weight loss 4.2 %. The highest constant that can be achieved addition fluorine is about 70 at room temperature, which more than 3 times greater nanocomposite. Nitrogen also enhances permittivity ambient but limit enhancement high lower activation energy.
