Perfect polymers

A potentially "transformative" approach to polymer films could be useful in microelectronic storage and photovoltaic materials, according Tom Russell of the University of Massachusetts Amherst. Russell's team, working with colleagues at the University of California Berkeley, have developed a faster, more efficient way to produce defect-free polymer thin films that have the smallest domains of block copolymers so far achieved that are densely packed and ordered. The uniformity and density of these films exploited in optical storage could allow the equivalent of 250 DVDs to be stored on a surface no bigger than a quarter.
