Conducting polymer as electrochromic material: Polyaniline
- Univ. of Rhode Island, Kingston, RI (United States). Chemistry Dept.
The authors have examined polyaniline as an example of conducting polymeric electrochromic materials. It exhibits multiple color switching and has the advantage of being amenable to molecular structure modification and morphological modifications. The novel properties of polyaniline are originated from its flexible and versatile molecular structure and the ability to conduct charge through its polymer backbone. At the present stage of research, more test data for material durability are needed. Photochemical stability, electrochemical stability and thermal stability of the device must be better than 7 to 10 years under usage conditions for application as smart windows in automobiles and buildings. Test data have just begun to accumulate. In time, the authors will be able to decide whether the material, in its present form, is durable enough or if it need to be improved. Future research on conducting polymer electrochromic device may take a route somewhat different from that of the other electrochromic materials. As they have shown in this chapter, there is a richer variety of ways to modify the properties of conducting polymer at the microscopic level than any other kinds of electrochromic material. They anticipate that molecular engineering will be very helpful as an additional tool to improve device performance and to accelerate the development of practical devices. The research on conducting polymer as electrochromic material is in its infant stage. The findings so far are encouraging, and the future appears to be promising. 58 refs., 18 figs.
