“…More and more researchers focused their attention on the controllable fabrication of anatase TiO 2 . Several methods were developed to form anatase TiO 2 , such as sol-gel methods [13,14], hydrothermal synthesis [15,16], flame synthesis [17,18], ultrasonic irradiation [19,20], chemical vapor synthesis [21] and liquid phase deposition [22,23].…”

“…Just as texture is used in the aforementioned examples to create superhydrophobicity, it can be used to create superhydrophilicity from an inherently hydrophilic material. With this strategy, superhydrophilicity is readily achieved from inorganic/organic LbL films, including those with inert particles such as silica or silicates or those incorporating photoactive particles such as titania . These superhydrophilic surfaces generated by LbL can be made using solid‐, spherical‐, or disc‐like nanoparticles but more complex geometries such as hollow TiO 2 100 and mesoporous SiO 2 spheres and a number of raspberry‐ or mulberry‐shaped particles have been created by the LbL method to generate superhydrophilic wetting surfaces .…”

“…The ability to tune a textured surface from superhydrophobic to superhydrophilic (switchable wetting) creates many possibilities. Water drops can roll off from areas of water sliding to areas of water pinning where they remain pinned and coalesce into larger drops . A wettability gradient ensures the motion of water droplets from superhydrophobic regions to superhydrophilic regions.…”

“…These include using superhydrophobic surfaces for saving energy, for example, reducing frictional energy dissipation at solid–liquid interfaces, and creating dropwise condensation to improve heat transfer rates, improve product lifetimes, such as self‐cleaning surfaces, or to be used in new technologies such as microfluidics. Superhydrophilic surfaces are of interest for applications such as antifogging and evaporative cooling . Superoleophobic or superoleophilic materials may be of potential use for oil/water separations…”

Controlled wetting at surfaces and interfaces is an important area of research with numerous potential commercial applications. Both superhydrophobicity and superhydrophilicity can be used to enable applications such as self-cleaning, dropwise condensation, or antifogging. Many strategies for creating such surfaces center around biomimicry, replicating the structure of the lotus leaf, for example. Given the potential impact, creating surfaces with these properties using any number of fabrication is of great interest. One very promising fabrication technique, however, for creating these surfaces is the layer-by-layer (LbL)-directed self-assembly of polyelectrolytes and other charged materials. LbL is a sequential adsorption technique wherein a surface is exposed to first a solution of one charge and then a solution of the opposite charge. LbL has many advantages, including the ability to incorporate many different types of materials and therefore functionality, the ability to conformally coat substrates of complex geometry, and environmentally friendly aqueous processing. This review describes recent progress in using LbL to create surfaces with controlled wetting.

Formation of alumina films with nano‐dot structures by successive liquid phase deposition, anodizing, and substrate dissolution

A process based on successive anodizing, liquid phase deposition (LPD), re-anodizing, and aluminium substrate dissolution to form alumina films with nano-dot structures is demonstrated. Initially, a protective oxide film is formed on the aluminium surface to prevent further dissolution of the aluminium substrate during LPD processing. Because of heterogeneity in the protective oxide film, localized dissolution would otherwise occur under the film, resulting in pit formation during the LPD treatment. During re-anodizing, these pits act as a mold for anodic oxide resembling a nano-dot like structure. Optimization of LPD parameters, such as time and temperature, would make it possible to obtain alumina films with nano-dot structures with sizes smaller than 1 mm. Alumina films with nano-dot structures with hollow can be realized by controlling the LPD conditions.
