Wettability Patterning
microfabrication applications, it is widely used to transfer the designed patterns from an etching mask to the substrate. When the sample is immersed into the etching bath, the etchant only contacts and reacts with the substrate surfaces where are uncovered by the etching mask. The suitable materials for the mask can be polymers or other materials such as photoresist, SU-8,SiO2 andSi3N4, which ...
متن کاملWettability Contrast Gravure Printing.
Silicon gravure patterns are engineered to have cells that are wettable and lands that are not wettable by aqueous inks. This strategy allows excess ink on the lands to be removed without using a doctor blade. Using an aqueous silica ink, continuous lines as narrow as 1.2 μm with 1.5 μm space are gravure printed.

متن کاملDroplet Lamella Lift Dynamics and Surface Wettability
Droplet impact on dry, smooth surfaces remains an issue for a variety of important applications such as fuel injection, spray cooling, metallurgy, pesticides and coatings. The mechanisms that initiate splashing are highly complex and differ from those on rough or pre-wetted surfaces. In this work, droplet wettability on a smooth, dry surface is examined to quantitatively evaluate its influence ...
متن کاملWettability 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...
