Deposition of copper sulfide on modified low-density polyethylene surface: morphology and electrical characterization
Applied Surface Science. Elsevier Science Bv, v. 202, n. 41732, n. 223, n. 231, 2002.
The modification of polyethylene surface has been used to obtain better interaction between organic polymeric surfaces and inorganic species. A previous treatment with modifiers is required in order to provide the adherence to the polymer surface. Our objective was the synthesis and the electrical characterization of copper sulfide coated low-density polyethylene (CuS-LDPE) films. SEM micrographs and AFM images showed a homogeneous distribution of copper sulfide, which contributes to the increasing of the electrical conductivity. X-ray analysis showed an increase of the copper sulfide crystals according to the number of immersions in the precursor sulfide solution. The measured conductivity of the CuS-LDPE films was in the range of 3.6-163.3 S cm(-1), according to the number of immersions on the precursor solution. (C) 2002 Elsevier Science B.V.
