DEVELOPED a "rewritable" paper that can be drawn or PRINTED on over and over again by changing the temperature. The new material consisted of three layers in a sandwich-like STRUCTURE where the text could be changed or wiped clean over 100 times by changing the temperature. According to a study published in the journal ACS Applied Material & Interfaces, the messages can last more than HALF a year, compared to other re-writable papers. It can be used in practical applications such as long-lasting INFORMATION recording and reading, rewritable label, reprintable display.
