Integrating Frontier Scientific Research into Polymer Physics Experiment Teaching:Taking the Preparation and Mechanical Properties of Antifreeze Ionic Gels as an Example
Polymer physics is a required course for polymer and material majors,and is extremely important in the development and application of polymer materials.Promoting teaching with scientific research is important ways to improve the quality of teaching in colleges and universities.In this paper,ionic liquid was used as multifunctional components(dispersible phase,antifreeze agent,plasticizer and conductive agent),and conductive ionic gels with antifreeze properties were prepared by photoinitiated polymerization of fluorinated ester monomers(2,2,3,4,4,4-hexafluorobutyl acrylate)and acrylic acid monomers.The effect of the content of antifreeze components on the mechanical properties,antifreeze and ionic conductivity of ionic gels was further investigated.This experiment can cultivate students'comprehensive experimental abilities and an in-depth understanding of the impact of polymer structure on performance.Through this experimental teaching reform,students can master knowledge principles and experimental skills,stimulate their enthusiasm for learning,and cultivate scientific thinking and scientific research innovation capabilities.
