AbstractThis work presents a reversible direct water-writing/electroerasing pattern on poly(3,4-ethylene dioxythiophene) inverse opals (PEDOT-IOs). The PEDOT-IO-0 is fabricated by potentiostatic polymerization of EDOT such that PEDOT infiltrates the interstices of a photonic crystal (PC) template, and the template is subsequently removed. The PEDOT-IO-I is obtained by reducing PEDOT-IO-0. There are four states and three different switches of PEDOT-IOs: the first switch is the irreversible reduction of PEDOT-IO-0 to PEDOT-IO-I (neutral state). The second switch is the reversible electrochemical process between neutral and oxidized PEDOT-IO-I accompanied by a reversible stopband shift owing to ionic doping/dedoping. The third switch is the water treatment process of PEDOT-IO-I (oxidation state) to form PEDOT-IO-II, which induces a blueshift in the stopband owing to water-induced removal of ions and shrinkage of the periodic structure. Combining the switches of PEDOT-IO-I and PEDOT-IO-II, a reversible water-writing/electroerasing procedure is realized in the full-solid state, producing multicolor patterns by water (a friendly ink) writing at different times. The as-prepared PC pattern could be erased electrochemically. Reversible e-paper can be successfully achieved based on the switches of PEDOT-IOs, providing a novel method for the fabrication of functional optic materials.
