%X As proposed by Herminghaus, a hierarchical structure could render any surface nonwettable as long as the roughness amplitude at small scales is sufficient to suspend a free liquid surface. Recently we reported that the wettability of La0.7Sr0.3MnO3, an intrinsic hydrophilic oxide, can be tuned from superhydrophilicity to superhydrophobicity by hierarchical microstructures generated by annealing the coatings of La0.7Sr0.3MnO3 powder in nanometric scale at different temperatures. Here we further demonstrate the similar phenomenon observed on LaMaO3 coatings, which conforms THAT the surface geometrical structure is a key factor to determine the wettability.
