Michael F. Rubner, Robert E. Cohen and colleagues point out that anti-fogging coatings that absorb water have been the focus of attention lately because of their ability to reduce light scattering and the resultant distortion caused by condensation. However, under extreme fogging conditions, these surfaces may frost and become foggy. They set out to make a better coating to withstand the aggressive conditions.Their report describes development and testing of a new coating that rapidly absorbs water molecules that cannot freeze in the coating. At the same time, the coating has a water-repelling or hydrophobic effect to larger water droplets. The hydrophobic character means that water droplets do not spread extensively on the coating but essentially remain as flattened droplets.The authors acknowledge funding from the Samsung Scholarship and the Materials Research Science and Engineering Centers (MRSEC) Program of the National Science Foundation.####About American Chemical Society (ACS)The American Chemical Society is a nonprofit organization chartered by the U.S. Congress.
