Xiaohong Gu, D T. Raghavan, Tinh Nguyen, Mark R. VanLandingham
Tapping mode AFM was used to examine the microstructure of polyester films before and after exposure to an alkaline solution. Bright-colored microgel domains and dark-colored interstitial regions were observed in phase images of the unexposed samples. The
