Zusammenfassung: | •Dopamine is used for the surface functionalization of 0.5(Ba0.7Ca0.3)TiO3-0.5Ba(Zr0.2Ti0.8)O3 filler•Mechanism of microstructure development in the composite has been explained.•The influence of dopamine in suppressing DC conductivity significantly and thereby improved electrical performances.•Potential for applications in energy storage and harvesting that can dramatically reduce excess energy loss emerges.
We demonstrate the potential of dopamine modified 0.5(Ba0.7Ca0.3)TiO3-0.5Ba(Zr0.2Ti0.8)O3 filler incorporated poly-vinylidene fluoride (PVDF) composite prepared by solution cast method as flexible energy storage and harvesting devices. Filler surface functionalization with dopamine acts as a bridging factor between the filler and the polymer matrix, resulting in better filler dispersion. The improved dielectric loss tangent ( |
