Environmentally Friendly Protective Coatings for Metals and Alloys
The operation and maintenance of machines and mechanisms, as well as outdoor structures, conducted by various industries across the board is a costly process due to corrosion of metals and/or alloys, from which the vast [...]
Zinc phosphate micro flakes as new corrosion inhibition additives in coatings and paints
Corrosion protection is a constant concern to steel manufacturers and users. Various processes were developed in the past to provide corrosion protection for steel such as metallic layers like e.g. zinc, coating of the metal [...]
Wettable Slippery Surfaces. Self-cleaning Effect and Mechanism
The phenomenon of self-cleaning displayed by the Lotus leaf and many other plant and insect surfaces has attracted tremendous attention recently. Self-cleaning surface is usually superhydrophobic and non-wettable, and is characterized by a very large [...]
A Bulk, Low Energy Surface Treatment for Three Dimensional Substrates via CVD Processing
There are myriad potential applications and a significant need for low energy surfaces. The gas-phase modification of three dimensional structures, such as fittings, tubing, valves, or manifold blocks, in high volume, to give hydrophobic and [...]
Silver nanoparticle-coated silica hybrid particles as anti-biofouling agent on filter materials
Pathogenic bacteria and viruses cause health problems and occasionally, lead to pandemic. Thus, global demand for clean air and safe water is increasing. Filtering systems have been utilized to provide clean air and water. However, [...]
Magnetically Aligned Nanotubes in Nanocomposite Membranes for High-Performance Filtration Applications
Ignacio-de Leon P., Chen X., Rabe E., Urgun-Demirtas M., Puga M., Zhou Z., Brotzman R., Argonne National Laboratory, US
Nanocomposite membranes, with magnetic nanotubes embedded in polyethersulfone (PES) membrane to form a permselective layer on microporous supports, are reported in this study for potential applications in wastewater treatment. Two new processes, alignment of nanotubes [...]
Commercial Applications of Oleophobic and Superoleophobic Membranes
We will present data on the performance of oleophobic and superoleophobic surfaces for a variety of commercial membrane and filter applications. It is well known that oleophobic surfaces create oil resistant, anti-fingerprint surfaces that are [...]
Hexadecane and water droplets impacting on amphiphobic surfaces
Veronesi F., Raimondo M., Guarini G., Boveri G., Institute of Science and Technology for Ceramics ISTEC CNR, IT
The control of surface wetting and the ability to actively modulate its response in different environments and against different liquids can make a bulk material a new functional one. In the field of materials science, [...]
Aligned HNT for Abrasion Resistance in Solar Cell Coatings
Halloysite nanotubes (HNT), a kind of naturally formed ceramics, encompass high aspect ratio, stiffness and low cost while remain understudied about their coating usage. Theoretical and experimental results have shown a modulus as high as [...]
Inherently Super-omniphobic Fibers and Fabrics
Truong Q., Zukas W., Welsh E., Stenhouse P., Brown P., Hoffman N., Mead J., Barry C., Mooney P., Sherer J., Panwar A., Koene B., Martin R., Cohen R., McKinley G., Kleingartner J., Chen D., U.S. Army Natick Soldier Research Development & Engineering Center, US
Work presented in this paper will introduce a process which modifies fiber geometry and its surface structure, and the resulting fabric’s weave structure with an additional structural level consisting of reentrant microtextural features that result [...]
Durable Superhydrophobic Coating
Bottom up cost-effective and durable superhydrophobic coatings were formulated using hydrophobic silica nanoparticles and epoxy binder at different epoxy-to-silica nanoparticle ratios. The localization of the silica nanoparticles in the dissolved epoxy oligomers before curing and [...]
Perfluoropolyethers as superhydrophobizing agents for carbon-based surfaces of fuel cell gas diffusion layers
Navarrini W., Sansotera M., Diamanti M.V., Pedeferri MP., Gola M., Dotelli G., Politecnico di Milano, IT
Perfluoropolyether (PFPE) peroxide has been employed in the functionalization of conductive carbon-based materials to confer them the highly hydrophobic surface properties of the perfluorinated materials. The thermal decomposition of a linear PFPE peroxide produced PFPE [...]
Hydrophobic treatment for jute fibres based on zinc oxide nanoparticles
The use of zinc oxide (ZnO) nanoparticles in the textile sector has been the subject of several studies aimed at making fibrous materials multifunctional and more resistant. This could open a wide range of new [...]
