Design of Polymer Chemistry Experiment"Preparation of Polyacrylamide Microspheres by Inverse Emulsion Method"
As expansion of theoretical teaching,experimental teaching has a significant effect on strengthening theoretical knowledge points and improving experimental practice ability of students.In order to meet the latest requirements for talents training,we optimized the content of experiments of polymer chemistry and designed the experimental project"preparation of polyacrylamide microspheres by inverse emulsion method".During the experiment,by changing multiple experimental conditions such as monomer concentration,dosage of initiator,students were guided to think about the influence of different experimental conditions on the particle size of the product,and students'understanding of the mechanism of inverse emulsion polymerization was deepened.Also,the students mastered the method of measuring particle size of product by using dynamic light scattering system in this experiment.
