Abstract:

This paper builds upon the university chemistry experiment "Electrochemical Preparation of Conductive Polymers". By incorporating molecularly imprinted polymers and elements of food safety, a simple task-oriented preparation experiment has been successfully transformed into a comprehensive experiment that combines the preparation of molecularly imprinted conductive polymers, performance characterization, and the highly selective detection of stimulants in beverages. The enriched and improved experiment content is engaging, relevant to real-world scenarios, and introduces cutting-edge analytical techniques, aiming to enhance students' integrated skills and fostering scientific thinking.
