Nano-SiO2/ low density polyethylene composite and micro-SiO2/ LDPE composite were prepared via a method of double-solution mixture. The discharging current of all samples after being prestressed at a DC electric field were recorded via Keithley 6517A. Currents of the both composites are less than those of pure LDPE. In addition, the curve shape of the nanocomposite is different from that of pure LDPE...
The composite of nano-SiOx and low-density polyethylene is prepared with the double-solution method. Charging currents of the composite at same dc stress, as well as discharging currents, are recorded with Keithley 6517A. It is found that the curves of charging and discharging currents decrease with charging times. Transferring those charging and discharging currents from time domain into frequency...
The dielectric behavior of a composite system of low-density polyethylene filled with nano-Ag is investigated with time-domain method at the room temperature (293 K). It is shown that the charging vs. time of the composite is lower than that of the pure low-density, however, the depolarization of the composite is faster than that of the pure low-density polyethylene. It seems that nano-Ag/LDPE composite...
The composite of nano-SiOx and low-density polyethylene is prepared with the double-solution method. Charging currents of the composite at different dc stress, as well as discharging currents, are recorded with Keithley 6517A. It is found that the curves of charging and discharging currents increase with electrical field. Transferring those charging and discharging currents from time domain into frequency...
