Surface Modification of Single-Wall Carbon Nanotubes by Photo-Initiated Chemical Vapor Deposition Utilizing Syngas

Hosseininasab S., Faucheux N., Soucy G., Tavares J.R., polytechnique montreal, CA

single wall Carbon nanotubes (SWCNTs) have various individual properties. These individual properties make them promising candidates for a wide range of applications, but their inherent hydrophobicity are the most challenging features for them. we propose [...]

Superhydrophobic Thermoset Elastomers with Excellent Stability to Rain Erosion and Water Immersion

Kujan E., Farshchian B., Xu Q., Feldman M., Lyons A., ARL Designs LLC, US

Polymeric materials with superhydrophobic surfaces are advantageous for industrial applications such as electrical insulators, roof membranes and seals because their surfaces are self-cleaning and remain dry when exposed to rain. However most superhydrophobic surfaces are [...]

Insect Fouling on Superhydrophobic Surfaces

Krishnan K., Milionis A., Tetteh F., Loth E., University of Virginia, US

An experimental setup consisting a wind tunnel and insect delivery system that is capable of injecting insects at 100 mph was built to test the effectiveness of superhydrophobic coatings towards insect fouling. Three distinct components [...]

Evaporation induced property change and hidden cavity formation

Kim I., Texas A&M University-Corpus Christi, US

Innovative optical techniques based on nano-biophotonics such as surface plasmon resonance (SPR) imaging are developed to characterize the transport and optical properties of nanofluids in situ, real-time, and full field manner. Al2O3 nanofluids (47 nm [...]

Elastic Superhydrophobic Nanocomposites with Enhanced Mechanical Durability

Milionis A., Languasco J., Loth E., Bayer I.S., University of Virginia, US

The vast majority of superhydrophobic surfaces are very fragile which is their main limiting factor for commercialization. Improving their mechanical durability has been a major issue during the last years. In this work we demonstrate [...]

Development of the Electro-Friction Effect in the Semiconductor Particles / Thermoplastic Resin Composite Film

Fuwa T., Su H., Yanaka R., Takase R., Kobayashi K., Kawai T., Sakurai K., Anzai H., Kuroda S., Gunma University, JP

Electro-Rheological (ER) fluid is the suspension of polarizable particles in an insulating solvent and has the characteristic that the apparent viscoelasticity changes when an electric field is applied from the outside. This phenomenon is caused [...]

Fine textured composite low friction coatings with combined corrosion protection ability

Becker-Willinger C., Kalmes P., Bentz D., INM - Leibniz Institute for New Materials, DE

A new class of multifunctional low friction coatings combining a low coefficient of friction of µ 1000 h in the neutral salt spray test on mild steel have been developed. The coatings possess a fine [...]

Directional wetting on chemically stripe-patterned surfaces

Kooij E.S., Jansen H.P., Zandvliet H.J.W., Univ. Twente, MESA+ Inst. Nanotechnology, NL

The ability to control liquids at surfaces is highly relevant for many application areas, including for example the performance and reliability of inkjet nozzles. Generally, the wettability of solid substrates can be modified both by [...]

Microscopic “Slide-Snap” Receding Contact Line Dynamics on Superhydrophobic Surfaces

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

Receding angles have been shown to have great significance when designing a superhydrophobic surface for applications involving self-cleaning. Although apparent receding angles under dynamic conditions have been well studied, the microscopic receding contact line dynamics [...]

Carbon Nanotube Bucky Papers with Tailored Porosity for Filtration Applications

Esawi A.M.K., Ramadan A.R., ElNur R., The American University in Cairo, EG

In this work, Carbon Nanotube Buckypapers (CNT-BPs) were prepared using vacuum filtration. Morphology and pore size distribution were investigated using scanning electron microscopy (SEM) and nitrogen gas adsorption. The prepared BPs were subsequently exposed to [...]
