X-ray photoelectron spectroscopy investigation of CuxS–CuyTe layers on polyamide film formed by the use of potassium telluropentathionate
Ingrida ANCUTIENĖ, Skirma ŽALENKIENĖ, Vitalijus JANICKIS

The phase composition of polyamide 6 (PA) films modified by layers of copper sulfides – copper tellurides, CuxS–CuyTe, was studied by the X-ray photoelectron spectroscopy method. Copper sulfide – copper telluride layers on the surface of PA film were formed by treating PA film samples in acidified 0.025, 0.05 and 0.1 mol · dm–3 solution of potassium telluropentathionate, K2TeS4O6, at a temperature of 1, 10 and 20 °C and then with Cu(II / I) salt solution. In the surface of PA samples modified by copper sulfides – copper tellurides, the presence of various copper, sulfur, tellurium and oxygen compounds (Cu2S, CuS, S8, CuxS, CuyTe, Cu(OH)2 and TeO2) was determined. Copper sulfides and tellurides tooke the major part in the layer; the content of copper sulfides in the composition of layers was higher. The copper sulfur–tellurium ratio decreased with increasing the duration of chalcogenization, in agreement with the results of the samples’ sheet resistance measurements since samples with the lower value of the copper : sulfur–tellurium ratio were more conductive.
