Three-dimensional microstructural diagrams of polymer nanocomposites (100 nm*100 nm*100 nm) with a one nanoparticle(np), b one vertical nanofiber(v-nf), c one parallel nanofiber(p-nf), d one vertical nanosheet(v-ns), and e one parallel nanosheet(p-ns). The applied electric field is along the direction of z axis with 10 MV m−1 and the volume fraction of nanofillers in different nanocomposites is set to the same value by adjusting the radius r, length l, or height h of nanofillers. The corresponding distributions of local electric fields (f–j) and local electric displacements (k–o) along the cross-section as the red dashed line shown. The arrows represent the sum of vectors in the y and z directions. p Calculated effective permittivity as a function of the permittivity of different nanofillers. q Schematic of depolarization effect using a simplified parallel laminated composite with an intermediate ceramic interlayer in yellow and two bilateral polymer layers in blue.
