Superhydrophobic 3D Printed Surfaces by Dip-Coating

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

Here we demonstrate a technique to fabricate three-dimensional superhydrophobic patterns. First a three-dimensional pattern was designed by 3D printing using acrylonitrile butadiene styrene (ABS) as printing material. A linear printing algorithm is followed for the [...]

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 [...]

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 [...]

Predicting Contact Angles for Regular and Irregular Surfaces

Krishnan K., Loth E., University of Virginia, US

We attempted new models for advancing and receding contact angles for both regular and irregular surfaces. While many models have been suggested for regular surfaces, comparison with experimental data shows the presence of secondary effect. [...]

Nanopatterned coatings for advanced glass products

McMackin I., Geddes J., Aryal M., Seitz O., Kobrin B., Rolith, Inc., US

A wide variety of glass products would greatly benefit from coatings that offer anti-reflective, anti-glare, anti-fog, anti-ice, self-cleaning, and other advanced functions. State-of-the-art coatings do not meet desired performance characteristics or cannot be applied over [...]

Superhydrophobic and Superhydrophilic Surfaces

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

A new generation of materials possessing a wide range of possible consumer applications such as water harvesting, stain resistant self-cleaning and water-repellent breathable surfaces are being fabricated. Based on nature’s example of the stenocara beetle, [...]

Effect of superhydrophobic nanocomposite surface roughness on anti-icing performance

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

While past work has shown the ice-phobic potential of a superhydrophobic surface or noted the effect of surface area on ice adhesion to an array of microposts, questions still remain on the effect of a [...]

1D Multi-Structured Micro/nanomaterials with Special Wettability

Zhao Y., Beihang University, CN

With the progresses in material sciences, the generation of microscopic materials experiences an architectural evolution process from simple to complex. The complex interior structures will enable such materials a number of potential applications. Here we [...]

Durability of a superhydrophobic nanocomposite coating under extended replicated rain impact

Davis A., Yeong Y.H., Steele A., Bayer I., Loth E., DeCombarieu G., University of Virginia, US

The objective of this study was to test the mechanical durability of a polyurethane/organoclay nanocomposite modified with perfluoroalkyl methacrylic copolymer in conditions that replicate extended rain impact. Samples were impacted with 1.4 mm droplets at [...]

Improving Resistance to Foreign Material for Hearing Instruments

Lin W., Starkey Labs, Inc., US

One of the recurring problems with hearing aids is the frequent exposure to moisture, wax and other foreign materials that can degrade and eventually hinder their performance. This issue may be exacerbated as the demographics [...]
