Influence of nanoparticle size on nucleation of electroactive phase and energy storage behaviour of zinc ferrite/ poly(vinylidene fluoride) nanocomposite

摘要: The incorporation of different size nanoparticles in polymer matrix plays a dominating role determining the overall structural, microstructural and electrical properties fabricated composites. In this paper, an investigation was done order to establish effect incorporating zinc ferrite (ZF) poly(vinylidene fluoride) (PVDF) matrix. incorporated spherical ZF nanoparticle induced nucleation electroactive phases PVDF by means electrostatic interaction between surface charge filler dipoles PVDF. fraction nucleated is strongly dependent on nanoparticles. There critical nanoparticle, below which efficiency diminishes as it may be swelled macromolecules. On other hand, if too large, there possibility formation mixed conformation polar nonpolar phase. Further, behaviour correlated with response composite where radius composite, exhibited maximum dielectric ferroelectric property. Finally, number participating chain interact were calculated model analysis represented schematically.
