Апстракт:
In this paper the dielectric properties, such as permittivity and loss tangent, of the printed nonwoven textile were studied in detail. The samples were screen printed using alginate paste (CHT-NV) with bentonite modified with sodium, copper and zinc ions in different percentages. Conductance and susceptance were measured in a broad frequency range and at temperature 298 K. It was analyzed how the addition of the previously mentioned bentonites affected the dielectric properties. A possible relationship between the concentration of copper and zinc in the samples and the value of the dielectric permittivity was considered. The sample with the highest concentration of zinc in the paste has shown the highest permittivity over the entire frequency range, while the dielectric loss tangent has very low values for all tested samples. The dependence of conductivity on frequency for these samples was also considered. Although this dependence was qualitatively the same for all samples, a certain change in the conductivity values can be observed.
