โœฆ Synopsis


The dielectric behavior of two kinds of Li and Ti co-doped NiO (LTNO)/polyvinylidene fluoride (PVDF) composite was studied at various different frequencies and temperatures. The effective dielectric constant of the percolative composite at 100 Hz is very high, i.e., e eff % 600, which is 60 times higher than that of the PVDF. The results also show that there is a remarkable difference in the dielectric constant of the composites with different LTNO fillers. Boundary layer capacitor effect and percolation theory can be used to explain the experimental results.
