摘要: Ceramic-polymer nanocomposites, consisting of surface hydroxylated cube-shaped Ba0.6Sr0.4TiO3 nanoparticles (BST–NPs) as fillers and poly(vinylidenefluoride) (PVDF) matrix, have been fabricated by using a solution casting method. The nanocomposites exhibited increased dielectric constant improved breakdown strength. Dielectric constants the nanocomposite with BST–NPs (BST–NPs–OH) were higher compared those their untreated composites. sample 40 vol % BST–NPs–OH had 36 (1 kHz). Different theoretical models employed to predict in order compare experimental data. BST–NPs–OH/PVDF composites also strength than BST–NP/PVDF counterparts. A maximal energy density 3.9 J/cm3 was achieved composite 5 BST–NPs–OH. This hydroxylation strategy could be used reference develop ceramic-polymer materials enhanced properties storage densities.
