The process and results of the formation of thin CuxSe layers on the polyamide 6 (PA) surface are described. For clarifying the influence of various factors (the concentration of the initial solution of potassium selenotrithionate, K2SeS2O6, pH, seleniumization time and temperature) the kinetics of the sorption-diffusion of selenium into PA from freshly prepared solutions of potassium selenotrithionate was studied. The CuxSe layers of various composition are formed on the surface of polyamide film if the seleniumized polymer is treated with the aqueous solution of Cu(II/I) salt. The concentration of copper in CuxSe layers formed is strongly dependent on the initial conditions of seleniumization. Some structural properties and electrical resistance values of obtained layers have been also investigated. The three phases - CuSe2, Cu2Se copper selenides and Cu2-xSe berzellianite - in the CuxSe layers were identified. The CuxSe layers formed on PA have electrical sheet resistance in the range of 49.8 to 2.5×105 /Omega Empty set.
