dc.description.abstract-translatedThe addition of tubular halloysite as a perspective type of mineral filler, even in only a few weight percent, can significantly affect the dielectric properties of base polymer. The resulting dielectric properties of the composite could also depend on the type of selected tubular halloysite. Specified types of this mineral filler obtained from different deposits can differ significantly in the shape and dimensions of individual nanotubes and even in the amount and composition of impurities in the resulting filler. All these influences can affect dielectric properties, as well as conditioning and treatment of the filler before incorporation into the polymer. This paper evaluates the effect of the choice of halloysite-based filler from different suppliers (different deposits) on dielectric properties of composites with the epoxy matrix. Firstly, several different types of halloysite-based fillers were tested to determine the effect of the filler type on dielectric properties of prepared composites. After that analyses were performed on prepared composites based on epoxy resin and with filling levels in the order of a few weight percent. All realized dielectric analyses were performed by dielectric broadband spectroscopy, and the values of the real part and imaginary part of permittivity were evaluated. It was found that the differences in estimated dielectric parameters between tested types of fillers are not as significant as expected, and only minor differences in the measured parameters were observed for prepared composites.en
