Spinning Multilayers of Polymers for LEDs.(research from Los Alamos labs)

Hsing-Lin Wang, a researcher in the Los Alamos Bioscience Division, described an innovative method for building multiple thin layers of polymer coatings using centrifugal force at the 222nd national meeting of the American Chemical Society. The new method, developed by Wang and Jeanne M. Robinson of the Los Alamos Chemistry Division, reduces thin-film production time and potentially improves the quality of thin-film devices.

Layers of very thin films of polymers are used in optical and electrical devices such as light-emitting diodes. For these applications, one or more layers of polymers, each about a millionth of a millimeter thick, are built up on a substrate such as glass, plastic, or metal. …
