doi:10.3866/PKU.DXHX202101010

Abstract

Abstract:

This study introduced a comprehensive experiment of green polymer chemistry. Phenylacetylene was polymerized by using organic rhodium complex as the catalyst in the aqueous solution. The molecular structure and photothermal properties of phenylacetylene (PPA) were characterized by fouriter transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), ultraviolet-visible spectrophotometer (UV-Vis), fluorescence spectrometer and thermogravimetric analyzer. Furthermore, this designed experiment is easy to operate and can use the solvent as a variable factor to inspire students to think actively. The experimental content covers the knowledge points of polymer chemistry, applied spectroscopy and polymer instrumental analysis and characterization. The implementation of this experiment can not only improve the students' comprehensive ability to use professional knowledge, but also cultivate the students' systematic scientific research thinking and environmental protection awareness.

Key words: Polymer comprehensive experiment, Polyphenylacetylene, Rhodium-catalyzed, Green chemistry
