A representative AFM topographic image (a) of latex PU/PMMA particles dip coated on a silicon wafer surface, amplitude of the AFM tip vibrations has been tuned to detect the morphology (core–shell structure) of the particles, and (b) of a monolayer of latex PU/PMMA particles spin coated on a silicon wafer surface at 2000 rpm from dilute water solution (<0.1 wt% of polymer), the diameter of the particles averaged along the dashed line is about 740 Å. |
