“Electrochromic behavior of layered WO3-polypyrrole films.”
Electrochromic materials are compounds that change color upon application of a voltage. Smart windows are a popular application of electrochromic materials. Smart windows yse a type of glass that changes the amount of light and heat allowed to pass through when a voltage is applied. Studies of the electrochromic behavior of these material when they are combined is limited. The focus of this summer project is to prepare and characterize a new method of preparing WO3-polypyrrole electrochromic devices. Measurement of the electrochromic behavior of the composites will be conducted using spectroelectrochemistry. The project will take independent measures of the electrochromic behavior of WO3 and polypyrrole, measure the electrochromic behavior of WO3-polypyrrole composite films, characterize the composite films by X-Ray Diffreactions, Infrared Spectroscopy and UV-Vis Spectroscopy and compare the effects of three different polypyrrole analogs.
