Figure 3

Representative atomic force microscopy (AFM) images of the silver-polyethyleneimine-polylactic acid (Ag-PEI-PLA) polymer composite obtained in the tapping mode. (a) A 3D AFM height topography large area scan of the Ag-PEI-PLA complex. (b) A 2D AFM phase large area scan of the Ag-PEI-PLA complex. (c) An enlarged view of the 3D AFM height topography scan of the Ag-PEI-PLA complex. (d) An enlarged view of the 2D AFM phase scan of the Ag-PEI-PLA complex. Relative humidity, ~50%; temperature, ~22–24°C.
