The dielectric properties and electrical conductivity of LDPE modified by fillers of biological origin

Abstract

In this work, were investigated about the investigation of the frequency-dependent change in the character of the dielectric permeability and the tangent of dielectric loss angles of the biocomposites type LDPE + x vol.% FB obtained by fish bone fillers adding to the matrix of low density polyethylene and the bionanocomposites type LDPE + x vol.% FB + 1 vol.% Al with adding to this mixture 1 vol.% aluminum nanoparticles size 50 nm, calculation the actual and imaginary parts of the dielectric permeability of these materials, and the investigation of frequency change of electrical conductivity of both bio and bionanocomposites. It has been established that the dielectric permeability of biocomposites practically does not change in the frequency range 0–103 kHz.

Dielectric properties of bionano-composites modified by fish scales

“…The content of the bio-filler in the composites varied from 1 to 15 vol.%. Biocomposites were prepared from a homogeneous mixture of powders of the matrix and filler components using a heated press at a temperature of 420 K and a pressure of 10 MPa [4]. The quenching crystallization mode occurs faster when the samples are cooled in a water-ice mixture.…”
