Abstract In order to introduce the frontier research field of phase change energy storage material to the undergraduates, a comprehensive chemistry experiment, preparation and characterization of phase change microcapsules containing tetradecanol, was recommended. The microcapsules containing tetradecanol were prepared by in-situ polymerization. The chemical structure, morphology and thermal storage performance of microcapsules were characterized by infrared spectroscopy, scanning electron microscopy and differential scanning calorimetry, respectively. Students can learn about the principle of condensation polymerization in polymer chemistry and in-situ polymerization of encapsulation by doing experiments. The testing and characterization of the products was helpful for students to clearly understand the function of infrared spectroscopy and differential scanning calorimetry. This comprehensive chemistry experiment can not only train the students' practical operations capability, but also develop their scientific innovative abilities.
