Abstract:

In this paper, we introduced a comprehensive chemical experiment in research-oriented university, the polyaniline film for supercapacitor featuring energy level visualization. The content included electrochemical polymerization of aniline, study of electrochromic properties, fabrication and properties of supercapacitor device, and its charge storage visualization. Through the practice, students will be able to further enhance the practical ability of scientific research on the basis of mastering experimental theory and experimental skills. The development of this experiment can also expose students to the frontiers of scientific research and cultivate students' ability to think independently and innovate continuously.

Key words: Polyaniline, Supercapacitor, Electrochemical polymerization, Electrochromic, Comprehensive chemical experiment
