In Situ Microstructure Control of Oriented Layered Double Hydroxide Monolayer Films with Curved Hexagonal Crystals as Superhydrophobic Materials

Oriented NiAl‐layered double hydroxide (LDH) films with micro‐/nanometer scale binary structures are prepared by in situ crystallization, without using any external aluminum source or shape‐directing surfactant, on a porous anodic alumina/aluminum substrate. The NiAl‐LDH film structures can be contr...

Zusammenfassung:	Oriented NiAl‐layered double hydroxide (LDH) films with micro‐/nanometer scale binary structures are prepared by in situ crystallization, without using any external aluminum source or shape‐directing surfactant, on a porous anodic alumina/aluminum substrate. The NiAl‐LDH film structures can be controlled by tuning crystallization temperature and time. Facile hydrophobic modification of the film surface leads to superhydrophobicity, as shown in the figure.
