Rewritable Paper

Researchers from Shandong University in China, the University of California, Riverside and Lawrence Berkeley National Laboratory have created light-printable, rewritable paper that can be printed with light and re-written up to 80-times. “The greatest significance of our work is the development of a new class of solid-state photo-reversible color-switching system to produce an ink-free light-printable rewritable paper that has the same feel and appearance as conventional paper, but can be printed and erased repeatedly without the need for additional ink. Our work is believed to have enormous economic and environmental merits to modern society,” said Yadong Yin, professor of chemistry at the University of California, Riverside.
