제목 The influence of ion conductivity in the reflective electrochromic display (R-ECD) device on the response time
초록 Reflective electrochromic display (R-ECD) based on the viologen-modified polymeric microspheres was prepared, and the relationships between the ion conductivity of device and response time were investigated. From our previous works, it was confirmed that the response times of the R-ECDs were affected by the particle properties. In this works, the differences of the response time of the R-ECDs were discussed utilizing the ion conductivity of the devices as shown in Scheme 1. Various properties of the viologen-modified polymeric microspheres were prepared, and the ion conductivities of each devices were examined by AC impedance. Response times were recorded using a white LED array spectrophotometer in combination with a digital multimeter as shown in Scheme 2.
