Teaching of Phase Separation of Polymer Solution by Number-shape Combination
The content of phase separation of polymer solution is one of the difficulties on polymer physics study.In this paper,the change of free energy of mixing of polymer solution after phase separation is deduced.By using the properties of image of convex and concave function,the section of phase separation of polymer solution is explained by method of number-shape combination,which can be well understood by most students and achieved good teaching effects.
