Effect of Support Structure on Permeance of Thin Film Composite Membranes

Ponnuru K., Lin H., Furlani E.P., SUNY-Buffalo, US

The production of potable water has become a worldwide concern to meet the demand of a growing population. The reverse osmosis (RO) membrane is the leading technology for desalination installations to produce drinkable water, due [...]

Merino Wool Surfaces Made Superhydrophobic

Herzog M.B., Johnston J.H., Victoria University of Wellington, New Zealand, NZ

Natural merino wool fibres have been used to fabricate wash-fast nonwoven textile surfaces with superhydrophobic and oleophobic properties. Wet felted samples were used to study the effect of the fibre diameter and the degree of [...]

Mechanically Durable Superhydrophobic Nanocomposites from Acrylonitrile Butadiene Styrene (ABS)

Milionis A., Yeong Y.H., Loth E., Bayer I.S., University of Virginia, US

We report on the development of nanocomposites based on a combination of ABS with hydrophobically modified fumed silica (HMFS). By tuning the ratio between the two materials we are again able to obtain static water [...]

3D Printered and Plasma Treated Superhydrophobic Mesh Filters for Oil-water Separation

Lee H.J., Lee S., Jo W., Lee H.J., Lee S., Moon M.-W., Korea Institute of Science and Technology, KR

We develop the 3D printed mesh filters with plasma treatment using a radio-frequency plasma-enhanced chemical vapor deposition (rf-PECVD) to control their surface wettability. The nano-sclae hairy structures on the meshes are created by plasma etching [...]

Bio-Inspired Multi-gradient Structure Surfaces for Water Collection/Repellency

Zheng Y., Beihang University, CN

Biological surfaces with micro- and nanostructures display unique wetting functions. Since spider silk collects water through a combination of multiple gradients in a periodic spindle-knot structure after wet-rebuilding process, a series of functional fibers with [...]

Durable Icephobic Coatings

Constantinou J., Panwar A., Mitra S., Nahum T., Wagner M., Dodiuk H., Barry C., Kenig S., Mead J., University of Massachusetts-Lowell, US

Accumulation of ice on the surfaces of windmills, airplanes, ships and telecommunications equipment hinders the efficient functioning of this equipmement, which can be overcome by the use of an icephobic coating. Prior work has established [...]

Advanced Coating for Energy Applications

Veedu V., Pollock J., Oceanit, US

Quest for oil and gas has increased in the past few decades and the industry is in a constant change of flux to identify new oil reserves and extraction methods to recover oil and natural [...]

Adhesion and friction between supported pH sensitive polymeric nanoparticles monolayers

Giraud L., Giasson S., Universty of Montreal, CA

The unique property of polymers responding to external stimuli has made this class of smart materials very promising for various applications. A particular approach that has been widely used over the past decades is the [...]

Droplet actuation and droplet mobility manipulation on porous media by means of backpressure control

Vourdas N., Stathopoulos V.N., Technological Educational Institute of Sterea Ellada, GR

Synthesis of surfaces with special tunable wettability as well as transitions between various wetting states are now intensively studied both for understanding wetting principles as well as for practical applications. Herein we present an alternative [...]

Development Antifog Nanohybrid Consisting of Polyestyrene Recycled Matrix by Sol-Gel Process

Hernández-Padrón G., Gómez-Quintero T., Blanco-Hernández A., UNAM, MX

A hybrid material consisting of SiO2 nanoparticles embedded in polystyrene recycled matrix has been developed. A polymer of polystyrene recycled functionalized (PSR-F) was used to influence the morphological and antifog properties of sol-gel synthesized silica [...]
