• Resumen

  • Polymer science represents an important area in industrial and research laboratories for chemists and material scientists. However, experiments involving polymers are uncommon in chemistry and material science curricula; therefore, an experiment involving polymers has been developed. This experiment has been used to teach fabrication of polymer films and to investigate the structure-property relationships of polymers using a multi-instrumental approach. It also introduces principles of Fourier transform infrared spectroscopy (FTIR) and how it can be utilized for polymer characterization. This experiment has been introduced successfully in a graduate-level instrumental analysis course in the chemistry department, but is also appropriate for an upper-level undergraduate course. It is simple to conduct in a teaching laboratory and utilizes commonly used instrumentation. Students gain hands-on experience in using multiple instruments. The experiment is designed to be completed in two to three weeks.
