Influence of the Magnetite Nanoparticles on Dielectric Properties of Nanocomposites on the Basis of Linear Polyethylene of Low Density-Juniper Publishers
Authored by Novikov GF The nanocomposite of magnetite/linear low-density polyethylene has been synthesized. Influence of magnetite nanoparticles in concentration 1-20wt% on dielectric properties and conductivity of nanocomposites in the range of frequencies 10-2-105Hz and temperatures from 113 to 383K have been studied. Inclusion of particles of magnetite in polyethylene slightly changed melting temperature. But at the same time an imaginary part of complex dielectric permittivity increased sharply (on two orders of size) and enthalpy of fusion decreased by 25J/g. Keywords: Linear low-density polyethylene; Magnetite; Dielectric properties; Electrical conductance Introduction Development of polymeric composition materials is one of the priority directions of development of modern technologies and the equipment. A unique combination of valuable properties of polymeric matriŃes such as film formation, mechanical stre...
