Özet
The article is devoted to the analysis of the main parameters of ZnO-polymer composites with different thicknesses. In the article, study the variation of dielectric permeability, which are the main parameters of ZnO-polymer composite varistors with different thicknesses, nonlinearity of volt-ampere characteristic (?) and opening voltage (Ucr) under normal conditions and under the influence of external factors. For this purpose, samples with thicknesses of 40, 180 and 300 ?m and different volume percentages (30÷60%) were prepared and their corresponding characteristics were measured. It should be noted that various experiments were conducted by changing the type of additives and polymers that make up the ZnO phase of the composite. As a result of the experiments, it was found that the preparation of composites with different thicknesses, as well as the types of additives and polymers significantly affect their electrophysical parameters.The opening voltage (Ucr) and the coefficient of non-linearity (?) of the volt-ampere characteristic, which are the main parameters of the composites, were determined. The most effective nonlinearity was observed in composites with a thickness of 180 ?m. The main parameters of the composites after modification and before modification were also measured in the work. In all cases, the dielectric constant (?) increased as the volume percentage of the composites increased. © 2024, International Organization on 'Technical and Physical Problems of Engineering'.
