| Abstract [eng] |
A polyamide 6 film if treated it with the water solutions of potassium pentathionate, K2S3(SO3)2, sorbs sulfur in the form of pentathionate anion. The concentration of sulfur in polyamide 6 film increases when increase of the concentration of solution of K2S3(SO3)2 and duration of polymer sulfuration. Further interaction of the polyamide 6 films containing sorbed S3(SO3)2 2− ions with Cu(I) salt solution leads to the formation of copper sulfide layers on the polymer surface. The concentration of copper in polyamide 6 films increases, when the temperature and the concentration solution of K2S3(SO3)2 and the exposure time of the polymer in solution of K2S3(SO3)2 were increased. The molar ratio of Cu : S in copper sulfide layers varied from 1 : 1.52 to 1 : 4.78. Results of X-ray diffraction analysis confirmed the formation of CuxS layers of various phases. Comprising in itself mainly phases of hexagonal chalcosine, Cu2S prevails in the composition of CuxS layers on polyamide 6 films surface. The sheet resistance of copper sulfide layers on PA 6 films varied from 4.30×103 to 7.05 kΩ/. |
