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'...
The Magnetic Induction (MI) communication techniques have enabled or enhanced many wireless applications in the indoor environments where line-of-sight (LOS) links usually do not exist. The position information of each wireless device in such complex environment can also be derived by the same MI systems without additional hardware or infrastructure. However, while MI signals can penetrate most transmission...
Electrostatic Force Microscope (EFM) was applied to study the origin and decay properties of surface charge on original and corona-resistant Polyimide films in micro-nanometer scale. The surface charge were generated by injecting on the surfaces of the polyimide (PI) films using the conductive probe of EFM. After the surface charge were characterized by EFM, the results indicate that the difference...
