| Abstract [eng] |
In recent years, nanotechnology and the potential of forming bio-nanocomposites by incorporation of nanosized particles in biopolymer matrices have drawn increased attention. So far, the most studied matrices for the bio-nanocomposites sythesis are various artificial and natural polyamides.The application of highmolecular compounds as matrix for the synthesis of selenium compounds- containing nanocomposites is of particular interest [1]. The present work aims to characterize the surface morphology of PA6/selenium compounds-containing bio-nanocomposites. These bio- nanocomposites were obtained applying different chemical synthesis methods: the PA6/Se via chemical bath deposition, the PA6/Cd-Se by successive ionic layer adsorption and reaction and the PA6/Ag-Cd-Se by cation exchange method. The bulk chemical composition was determined using atomic absorption spectroscopy (AAS). Atomic force microscopy (AFM) was used to characterize surface morphology. From the AFM images (Fig. 1), it can be seen that the local areas of the PA6 and PA6/Se surfaces exhibited a different morphological structure. Surface roughness is also an important parameter for quantitatively describing the surface. The Zmean and Ra of PA6/Se composite were clearly different from those of the virgin PA6 (Table 1).
