In Situ Techniques for Monitoring Electrochromism: An Advanced Laboratory Experiment
Saricayir, Hakan; Uce, Musa; Koca, Atif
Journal of Chemical Education, v87 n2 p205-207 Feb 2010
This experiment employs current technology to enhance and extend existing lab content. The basic principles of spectroscopic and electroanalytical techniques and their use in determining material properties are covered in some detail in many undergraduate chemistry programs. However, there are limited examples of laboratory experiments with in situ instrumental techniques for technological applications in the real world. Thus, we introduce two examples of more recent in situ experimental methodology: in situ spectroelectrochemical and in situ electrocolorimetric methods. This experiment introduces students to (i) electrochromism methodology, (ii) thin-film preparation techniques of electrochromic materials, (iii) application of in situ spectroelectrochemical and in situ electrocolorimetric techniques to monitor electrochromism, (iv) design of an electrochromic display device, (v) demonstration of electrochemical writing with an electrochromic display device, and (vi) usage of an in situ electrocolorimetric technique for determining the color parameters of electrochromic materials. (Contains 3 figures.)
