The article describes each stage of the autocatalytic electroless metallization process of thermoplastic polymers produced with 3D printing technology. In particular, the influence of the preparation of the sample's surface layer on the quality of the finished metallic coating was assessed. Samples made of polylactide filament and polylactide with the addition of copper were subjected to metallization. In the metallization process, six different etching solutions were prepared to etch the polymer’s surface layer. The concentration of sulfuric acid VI was 200g/dm³ or 100g/dm³, sodium hydroxide 100g/dm³, and potassium permanganate 50g/dm³ or 20 g/dm³. The microscopic analysis and measurement of the arithmetic mean of the ordinates of the surface roughness profile of the samples for the selected process steps are presented.

W artykule opisano wyniki badań nad nowymi materiałami polimerowymi elektroprzewodzącymi do budowy superkondensatorów, skonstruowanych na bazie polipirolu. Wykonano pomiary ich charakterystyk częstotliwościowych zespolonej impedancji metodą elektrochemicznej spektroskopii impedancyjnej (EIS). Do zamodelowania impedancji tych elementów przyjęto wybrane, znane w literaturze modele ułamkowego rzędu. Do estymacji parametrów tych modeli wykorzystano algorytm optymalizacyjny roju cząstek (z ang. Particle Swarm Optimization – PSO).

The paper presents the results of research on new electroconductive polymer materials, based on polypyrrole, for the construction of supercapacitors. Measurements of the complex impedance frequency characteristics were performed for these elements using electrochemical impedance spectroscopy (EIS) method. Selected fractional-order models, known from literature, have been used to model the impedance of these elements. The Particle Swarm Optimization (PSO) algorithm has been used to estimate parameters of these models.
