2013 m. Nr. 1 Morphological study of silver sulfide layers on the polypropylene surface
Layers of silver sulfide, Ag2S, on the surface of polypropylene (PP) film were formed by the chemical bath deposition method (CBD). An initial treatment of PP with modifiers is required in order to provide the adherence to the polymer surface. Film samples were characterized by X-ray diffractometry (XRD), optical microscopy, scanning electron microscopy (SEM) / energy dispersive X-Ray (EDX) analysis and atomic force microscopy (AFM). XRD and EDX methods confirmed that on the surface of the polypropylene film a layer of silver sulfide was formed. The surface morphology, texture and uniformity of the silver sulfide layers formed on the PP surface depend on the number of polymer immersions into the precursor solution. The formation of silver sulfide layers proceeded irregularly in the form of islands which grew into larger agglomerates. Keywords: Ag2S, polypropylene, surface modification, XRD, SEM, AFM |
