Application of Polymer Physics Teaching Content in the Teaching of Plastic Materials and Formulation Design——Taking"Polymer Chain Structure"as an Example
Polymer physics,as a core course in the field of polymer science,focuses on the unique physical properties of polymers.The teaching content related to polymer chain structures explains the relationship between the chemical structure and physical properties of polymers,forming the foundation for understanding the macroscopic properties of polymer materials.Plastics,as a major category of important polymer materials,are diverse and complex,with performance differences even among different grades of the same type of plastic.As a precursor course,the teaching content of polymer physics plays a crucial guiding role in the study of plastic materials.This paper uses"polymer chain structure"as an example to explain how variations in the sequence structure of molecular chains,molecular weight and its distribution,and chain topology affect the physical and processing properties of plastics.The use of commercial plastic products as examples enhances the effectiveness of teaching.Students are encouraged to establish connections between the content of different courses,thus building continuity in the teaching content of polymer science.It is of great significance to cultivate students'ability to construct a systematic knowledge framework in polymer science for their learning and mastery of the subject.
