MIT Researchers Create Anti-Fogging, Self-Cleaning Glass
05/31/2012

MIT researchers found a way to make glass that’s anti-fogging, self-cleaning and free of glare. A new way of creating surface textures on the glass, consisting of an array of nanoscale cones, also virtually eliminates reflections. The surface pattern is based on a new fabrication approach the MIT team developed using coating and etching techniques adapted from the semiconductor industry.

The antireflective and anti-fogging capabilities would be useful on optical devices in humid environments. On touch-screen devices, the glass would not only eliminate reflections, but would also resist contamination by sweat. Solar panels would be made more efficient as neither reflection nor dust and dirt accumulation would affect the transmission of light through the glass. Even car windows could benefit by cleaning themselves of dirt and grit, eliminating glare, and preventing fogging on the interior surface.
