BiFeO3/LDPE nano-dielectric films of different BiFeO3 nanoparticles percentages including 0.5%, 1%, and 2% have been successfully prepared using solution-melt blending method in the spiral double pole rheometer. The BiFeO3/LDPE nanocomposite films were characterized by SEM (scanning electron microscopy), FT-IR (Fourier transform infrared), and XRD (X-ray diffraction). The dielectric properties were...
Type NaY zeolite powder with nanoscale and micronscale were doped in low-density polyethylene(LDPE). The zeolite particles with nanoscale and also with micronscale were uniformly distributed in LDPE shown in SEM images. The dielectric spectra of LDPE/zeolite composites and pure LDPE are tested by broadband dielectric spectrometer at two different temperatures, 293K and 353K. The study found that composites'...
Use type 4A nanoscale zeolite powder composite with Low-density polyethylene(LDPE), obtained the different of doping concentration of composite materials which the zeolite weight percentage are from 0.5wt% to 3wt%. By using broadband dielectric spectrometer measure and analyse the dielectric performance in a relatively wide frequency range to LDPE/zeolite composite and pure polyethylene at different...
Low-density polyethylene (LDPE)/pumice composites with different pumice weight percentage (1 wt%, 2 wt% and 5 wt%) were prepared by melt blending process in torque rheometer. Space charge distribution in composites and pure LDPE were investigated with pulsed electro-acoustic method (PEA). The results indicate that most of the space charge in pure LDPE under high electrical field was homo-polarity...
