Paper title: WATER AND THERMAL AGING INFLUENCE ON DIELECTRIC RESPONSE OF LOW DENSITY POLYETHYLENE-AL2O3 NANOCOMPOSITES

Author(s): FLORIN CIUPRINA, LAURA ANDREI,

Abstract:

Water and thermal aging influence on the dielectric response of low density polyethylene (LDPE)-Al2O3 nanocomposites with 2 wt% filler content was discussed in this paper. The dielectric response, consisting in frequency variation in the range 10 mHz 1 MHz and for temperatures from 30 to 70 C of the real and imaginary parts of the complex permittivity, measured before any treatment, after one week immersion in deionized water and after three stages of thermal aging at 90 C are presented and discussed in this paper, with a focus on the stability of the dielectric properties to the applied stresses.
