Superhydrophobic cellulose nanocomposites
Journal of Colloid and Interface Science, 2008Superhydrophobic cellulose nanocomposites were prepared using a multi-step nanoengineering process. The combination of different techniques made it possible to construct novel features at the ensuing surface, characterized by both an increase in its roughness induced by amorphous silica particles and a reduction in its energy insured by perfluoro ...

Superhydrophobic Coatings for Microdevices
Journal of Adhesion Science and Technology, 2008We have developed two simple techniques to impart superhydrophobic properties to the surfaces of microdevices. In the first approach, thin films of a fluoropolymer were spin-coated on the device surfaces followed by an oxygen plasma treatment. By varying the oxygen plasma treatment time, the water contact angles on device surface could be tuned from ...

Fabrication Of Superhydrophobic Surfaces
Journal of Adhesion Science and Technology, 2008Superhydrophobicity has recently drawn a great deal of attention from both fundamental and practical application points of view. This paper summarizes the basic principles involved in creation of superhydrophobicity and reviews the diverse methods recently developed to make superhydrophobic surfaces and coatings.

It is common sense that the droplet is stickier to substrates with larger solid-liquid contact areas. Here, we report that this intuitive trend reverses for hollowed micropillars, where a decrease in solid-liquid contact area caused by an increase in the pore size of a pillar top leads to an increase in the droplet depinning force.

BIOMIMETIC SUPERHYDROPHOBIC SURFACES
2014Inspiration from nature has been widely used in the development of new materials and in the improvement of their properties. Superhydrophobic surfaces inspired in species present in nature with highly water repellent self-cleaning properties — such as the well-known lotus leaf — are interesting examples of the biomimetic approach for the development of
