2010 m. Nr. 1 Atomic force microscopy study of the morphology of copper sulfide layers formed on polyamide film surface
The morphology of polyamide PA6 films modified by copper sulfide layers was studied by the atomic force microscopy method. Copper sulfide, CuxS, layers on the surface of PA6 film were formed by treating PA film samples in dodecathionic acid, H2S12O6, 0.002 mol · dm–3 solution and then with Cu(II/I) salt solution. Formation of copper sulfide layers was found to proceed unevenly, in the form of islands which later grew into agglomerates. The surface of the layers was relatively uneven and rather rough. The thickness of CuxS layers increased with increasing the duration and temperature of polymer treatment in H2S12O6 solution. The same tendency was observed in the change of surface roughness: it increased with prolonging polymer treatment in H2S12O6 solution and with increasing in the solution temperature.
