IT House December 12 news, according to the university of science and technology of China official website, recently, the university of science and technology of China Yu Shuhong academician team designed a new type of nanowire assembly based on nanowire assembly multi-color display electrochromic device, the device has specific optical, electrical and multi-color display characteristics.
According to reports, compared with the general electrochromic device, the advantages of the device are reflected in the following two aspects:
1. Since the W18O49 and V2O5 nanowires display different colors at the same applied voltage, the nanowire co-assemblies can exhibit dynamic color changes from orange, green to gray when biased at 2 V, 0 V, and -0.5 V. By controlling the proportion of the two nanowires, the electrochromic properties of the co-assembled films can be controlled, including color display, transparency, response time, and coloring rate.
2. Various patterns and components can be constructed with the assistance of lb technology with the assistance of the mask plate to achieve more complex color display and information transmission.
IT Home learned that electrochromic devices are mostly prepared based on brittle ITO substrates and require an external power supply system to drive the work, which affects the flexibility, independence and portability of the devices. At present, the development of self-powered electrochromic devices with flexible and mechanical stability is still challenging. The research results provide a new way for the development of high-performance multicolor display and flexible self-powered electrochromic devices.
