The Institute of Materials Research and Engineering in Singapore has developed a new plastic with high anti-reflective properties.
Only 0.09 to 0.2 percent of the visible light hitting the surface of the new plastic is reflected. That equals or betters existing anti-reflective and anti-glare plastics on the market which typically reflect 1 percent of visible light, IMRE claims. Applications include television displays, windows and solar cells.
“The new plastic was made possible because of the unique nanoimprint expertise that we have developed at IMRE,” says Low Hong Yee, the senior scientist leading the research. Several companies are licensing the anti-reflective nanostructure technology from Exploit Technologies Pte. Ltd., the technology transfer arm of the Agency for Science, Technology and Research, which oversees IMRE.
The technology relies on nanoprinting, which changes the plastic's physical properties without the use of chemicals. It has evolved from lithography technology used in the semiconductor industry. Researchers can create unique, complex structures similar to a moth's eye where nanometer-sized particles are placed on top of other microstructures. The structure allows a wider operating angle than conventional structures, IMRE claims.
