Double-solution mixture method was employed in the preparation of the composite of low density polyethylene/Nano-silver. Space charge distributions in samples with different nano-silver concentrations were measured using the pulsed electro-acoustic (PEA) method. In the experiment, samples were tested under three different levels of electrical stress, respectively: 10kV/mm, 30kV/mm and 50kV/mm. Discharge...
High field conduction of the composite of nano Ag/low-density polyethylene (LDPE) and pure polyethylene is studied, as well as the effect of the contents of nano Ag on high field conduction. Schottky effect, Poole-Frenkel effect, space-charge-limited conduction (SCLC), and ion hopping conduction are used to fit the results. It is pointed out that both space-charge-limited conduction and Poole-Frenkel...
Nano-SiOx and micro-SiO2 particles were homogeneously dispersed in low-density polyethylene with a method of double-solution mixture. Both kinds of the composites were sputtered with Au and Ag on both surfaces as electrodes, respectively. Space charge in the composites was investigated with pulsed electro-acoustic method (PEA). It is shown that space charge distribution in the sample with different...
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...
