Figure 9(a) and (b) show the SEM micrographs of the 3 M® scotch tape before and after peel-test, respectively. After peel-test, a few tiny white particles detached from the hydrothermal grown ZnO layer could be observed on the surface of 3 M® scotch tape. Nevertheless, the surface morphology of the hydrothermal treated nano-ZnO/P(MMAco- BA) nanocomposites hardly changed after peel-test as shown in Fig. 9(c), indicating the strong adhesion of the newly formed ZnO on the surface of nano-ZnO/P(MMA-co- BA) nanocomposite.
