Abstract
Three-dimensional (3D) BaTiO3 (BT)/melamine foam (MF)/polyvinylidene fluoride (PVDF) nanocomposites were designed by introducing PVDF solution into a continuous 3D BT/MF network, which can further enhance energy storage performance. The results show that compared with the neat PVDF, the energy density of the 3D BT/MF/PVDF nanocomposites material can be doubled at low field, and the energy density is increased by 25.69 times at the breakdown field strength of 100 KV/cm. The preparation of two-dimensional (2D) plate-like BT follows the reaction mechanism of in situ topology, wherein MF provides a dispersion site for BT in the nanocomposites, thereby changing the direction of carrier transport in the MF polymer matrix. The design of this structure can achieve the enhancement for energy storage density under low filling volume fraction, which has certain research value and significance.
