Solution-Grown Zn/Al Layered Double Hydroxide Nanoplatelets onto Al Thin Films: Fine Control of Position and Lateral Thickness

Figure 4

SEM images of the LDH nanoplatelets formed at 75°C with different aluminum layer thickness for a growth of 12 h: (a) Al thickness of 30 nm; (b) Al thickness of 100 nm; (c) ideally infinite Al thickness. (d) Mean value of LDH nanoplatelet thickness as a function of the original aluminum thickness (20 nanoplatelets measured for each point).
