摘要
Abstract
Nano Fe3O4 is a typical paramagnetic material,and its doping into low density polyethylene（LDPE） may affect the magnetic,dielectric and other properties of the LDPE matrix.To research the influence of doping nano Fe3O4 on the dielectric properties of LDPE,we prepared Fe3O4 ferrite nanoparticles used for preparation of polyethylene（PE） composite by the chemical co-precipitation method and modified by different methods,and prepared the nano Fe3O4 and LDPE composite materials with different mass fractions from 0.25% to 1% by melt blending.Moreover,we investigated the relationship of permittivity and dissipation factors dependence of frequency by broadband dielectric spectrometer.The conclusions can be drawn that doping Fe3O4 and magnetization will affect permittivity and dissipation factors,and the influential degree is related to the doping methods and quality percentage of Fe3O4 ferrite nanoparticles.关键词
