title = "Investigation on the dielectric properties of nano-titanium dioxide - Low density polyethylene composites",
abstract = "Dielectric properties of nano-titanium dioxide (TiO2) with diameter about 25nm - low density polyethylene (LDPE) composites were investigated at the temperature ranging from 293K to 343K with the frequency ranging from 0.1Hz to 100kHz in the present paper. Experimentally, we observed two peaks in the spectrums; one appears in both pure and incorporated LDPE (abbreviated as peak A) while the other appears only in the samples with nano-TiO2 content exceeding 1wt\% (abbreviated as peak B). The activation energies calculated from dielectric spectrum for peak A and peak B are 1.09eV and 0.8eV respectively; they are independent of the concentration of TiO2 nanofiller. Furthermore, the position of peak B is also independent of the nano-TiO2 content in the frequency spectrums. Thus, it is reasonable to conclude that peak B is intrinsic, corresponding to the α response of LDPE while peak A may originate from the traps at the {"}Interaction Zone{"} around the nanoparticles. The dielectric properties of nanocomposite were determined by such {"}Interaction Zone{"}.",
