Fabrication of Nanostructured Polyamic Acid Membranes for Antimicrobially Enhanced Water Purification

Figure 6

Scanning Electron Microscopy (SEM) image of wet phase inverted Au/Ag-PAA film. The main image shows the enlarged image of the solid circled part of the inset at a magnification of 5000x. The surface of the film shows well-dispersed gold (circles with a double line), silver nanoparticles (circles with a dashed line), and pores on the polymer surface (circles with a single line).
