摘要

An electrothermochromic paper display composed of colorimetrically reversible polydiacetylenes (PDAs), utilizing screen printing on photopaper and patterning of electrically conductive wires on the reverse side, was developed. Heat generated by passing a current through the wires on the back of the photopaper induced a bluetored color transition of the PDA on the front at regions corresponding to the wires. This resulted in the generation of redcolored images, which disappeared when the supplied electric current was removed. The voltage at which the PDAs changed color could be controlled by using structured diacetylene (DA) monomers. A PDAbased sevensegment display has also been developed. By applying voltages, redcolored numeric digits from 0 to 9 can be displayed on the surface of the PDA layer. Keywords: polydiacetylene, paper display, electrothermochromism
