| Abstract [eng] |
The deposition of copper sulfide as a thin layer onto the surface of the polymer is a promising approach to obtain electrically conductive films. Flexible, transparent polymer substrate coated with copper sulfide is expected to be useful in many fields, for example, as reflectors for concentrating collectors, heat mirrors, and solar control coatings [1], as conductive substrates for deposition of metal and semiconductors [1, 2], as gas sensors functioning at temperatures close to room temperature [3]. The chemical bath deposition (CBD) technique has been used for the deposition of copper sulfide thin films on polypropylene (PP) substrates. The CuxS thin film deposition was carried out at room temperature using a mixture of 0.05 M CuCl2 and 0.05 M Na2S2O3 solutions for 16 h. The CBD process was carried out by varying cycles (1, 2 and 3 cycles) of deposition. The formed samples were annealed at 80 ºC for 30 min. The structure, surface morphology, and optical characterization of the deposited thin film indicated a strong relationship between the number of deposition cycles. The scanning electron microscope (SEM) showed a uniform morphology with randomly oriented nano-grains of the copper sulfide film at varying deposition cycles (Fig.1). The thin film morphology uniformly covers the PP substrate and shows a smooth surface. Additionally, the films prepared by CBD with 3 cycles were found quite dense with good crystallinity and no holes, homogenous surface, adhesion to the substrate, compact, and improved in grain size compared to copper sulfide films prepared with 2 cycles (Fig. 1.). |
