It sounds like it's not just us that spend half our sweet time with lint-free cloth in hand. Researchers at
MIT have developed a new type of glass that "virtually eliminates" reflections, and is also water-repellent. By using techniques from the semiconductor industry, conical nano-textures etched into the layered surface that give the wonder-glass its fog, glare and self-cleaning properties. The hope is that the technology will find its way into our many daily screens and even windows. It's not all about gadget vanity though; solar panels lose efficiency over time through residual surface build up, and using the new glass could go some way to eliminate that issue. If they can just remember where they put the ultra-clear test sample that is.
One of the most instantly recognizable features of glass is the way it reflects light. But a new way of creating surface textures on glass, developed by researchers at MIT, virtually eliminates reflections, producing glass that is almost unrecognizable because of its absence of glare — and whose surface causes water droplets to bounce right off, like tiny rubber balls.
The new "multifunctional" glass, based on surface nanotextures that produce an array of conical features, is self-cleaning and resists fogging and glare, the researchers say. Ultimately, they hope it can be made using an inexpensive manufacturing process that could be applied to optical devices, the screens of smartphones and televisions, solar panels, car windshields and even windows in buildings.
The technology is described in a paper published in the journal ACS Nano, co-authored by mechanical engineering graduate students Kyoo-Chul Park and Hyungryul Choi, former postdoc Chih-Hao Chang SM '04, PhD '08 (now at North Carolina State University), chemical engineering professor Robert Cohen, and mechanical engineering professors Gareth McKinley and George Barbastathis.
