Nanodiamond-dispersed Transparent Screen Developed

Associate Professor Koichi Sakajiri, Associate Professor Masatoshi Tokita, and their colleagues in the Graduate School of Science and Engineering at the Tokyo Institute of Technology developed highly refractive nanodiamond^(*) -dispersed film with high transparency and good light diffusion properties. Whereas it is transparent enough to see through, it can be used as a transparent screen to project images - beautifully and without color irregularities.

The film is expected to be used to display ads and other information as necessary on high-rise buildings, show windows, exhibit windows in aquariums and zoos, and head-up displays in vehicles. Made of diamonds, it has a hard, solid surface with resistance to scratching.

Since transparent boards made of glass, plastics and other materials are indispensable for our daily life, the ripple effect of this development is enormous. This outcome was presented at the 63rd Annual Meeting of the Society of Polymer Science held at the Nagoya Congress Center in Atsuta Ward, Nagoya, from May 28 to May 30, 2014.
