Wettability of ceramic surfaces -A wide range control of surface wettability from super hydrophilicity to super hydrophobicity, from static wettability to dynamic wettability

Wettability Study of Super-Hydrophobic Silica Aerogel Powders

Due to the importance of super-hydrophobic silica aerogel powder as a material in the field of energy saving, its wettability in the presence of various surfactants was investigated. One anionic and two non-ionic surfactants with different molecular structures were used as wetting and dispersing agents. Wetting properties of the aerogel powders were investigated by the contact angle measure...

Wettability of Nanostructured Surfaces

There are many studies in literature concerning contact angle measurements on different materials/substrates. It is documented that textiles can be coated with multifunctional materials in form of thin films or nanoparticles to acquire character‐ istics that can improve the protection and comfort of the wearer. The capacity of oxide nanostructures to inhibit fungal development and neutralize ba...

Control of surface wettability via strain engineering

Reversible control of surface wettability has wide applications in lab-on-chip systems, tunable optical lenses, and microfluidic tools. Using a graphene sheet as a sample material and molecular dynamic simulations, we demonstrate that strain engineering can serve as an effective way to control the surface wettability. The contact angles θ of water droplets on a graphene vary from 72.5◦ to 106◦ ...

Control surface wettability with nanoparticles from phase-change materials

Bioinspired surfaces with special wettability.

Biomimetic research indicates that many phenomena regarding wettability in nature, such as the self-cleaning effect on a lotus leaf and cicada wing, the anisotropic dewetting behavior on a rice leaf, and striking superhydrophobic force provided by a water strider's leg, are all related to the unique micro- and nanostructures on the surfaces. It gives us much inspiration to realize special wetta...
