Nanobubbles yield super non-stick surfaces

Upton, NY | Posted on April 13th, 2010

These nanocavities trap tiny bubbles which render the surface extremely water repellent, say researchers at DOE's Brookhaven Lab, who recently captured the first glimpse of these miniscule air bubbles. Their work could lead to a new class of non-stick materials for a range of applications, including improved-efficiency power plants, speedier boats, and surfaces that are resistant to contamination by germs.

The water-shedding effect, called "superhydrophobicity," occurs when air bubbles remain trapped in the textured surface, drastically reducing the area of liquid in contact with the solid. This forces the water to ball up into drops that readily roll off.

To glimpse the nanoscale air bubbles, the scientists created a regular array of more than a trillion nanocavities on an otherwise flat surface, coated it with a wax-like surfactant, and watched how x-rays diffracted off the surface. The measurements revealed air bubbles measuring about 10 nanometers in diameter (ten thousand times smaller than the width of a single human hair) that kept water from penetrating any more than 5 to 10 nanometers into the cavities. This coated, nanotextured surface was much more water repellant than the flat surface alone, with features that make it attractive for a wide range of applications.

About DOE Pulse
DOE Pulse highlights work being done at the Department of Energy's national laboratories. DOE's laboratories house world-class facilities where more than 30,000 scientists and engineers perform cutting-edge research spanning DOE's science, energy, National security and environmental quality missions. DOE Pulse is distributed twice each month. Each issue will include research highlights, updates on collaborations among laboratories, and profiles of individual researchers.

DOE Pulse is published in both HTML and PDF formats. The HTML version can be accessed with any web browser; the PDF version requires the use of Acrobat Reader software, which can be downloaded at no charge. The HTML Pulse contains extra research highlights which, because of limited space, aren't in the PDF or printed issues. On the other hand, the PDF Pulse retains the format of the printed version and enables you to print high-quality paper copies for faxing, mailing, etc.
