It was expected that elemental copper or zinc introduced into polycaproamide would interact with amide groups of the polymer and that the materials would be characterized by semiconductor properties. To prove this theory, resistivity at several temperatures was determined and thermal activation energies calculated. As the metal contents were relatively low, metallic conductivity was avoided. Temperature‐resistivity dependence and a negative temperature coefficient of the resistivity prove that polyamide–metal compositions can be classified as semiconductors.
