| Abstract |
The abnormally enhanced dielectric properties of poly(vinylidene fluoride)/nano-sized La2NiO4-d (PVDF/LNO) nanocomposite films were investigated. To study the effects of surface modification of LNO nanoparticles caused by a combustion process on the formation of a percolating network and interfacial polarization, micro-sized LNO was also used as filler. The abrupt changes in the dielectric permittivity (e') and loss tangent (tand) of PVDF/LNO composites were observed, indicating the formation of percolation network of LNO filler particles. e' of the nanocomposites was larger than that of the microcomposites. Significantly improved dielectric properties with e' = 431.17 and tan = 0.43 were successfully achieved by optimizing loading content of LNO filler to be 25 vol%. Large interfacial polarization intensity due to nano-sized filler particles and modified-surface LNO particles were suggested to be primary causes for improving the dielectric properties of PVDF/LNO nanocomposite films. |
