polyethylene composite films, thermal activation spectroscopy, differential scanning calorimetry, relaxation, electrically active defectsAbstract
α-relaxation in composite films of low-density polyethylene with soot particles was investigated through thermostimulated depolarisation and differential scanning calorimetry. It is shown that the joint application of these methods can be used to determine the number of relaxers involved in the relaxation processes of a polymer above its glass transition temperature. The parameters and the number of electrically active defects in composite polyethylene films filled with different percentages of technical carbon are calculated.
