Single Molecule Dynamics Teaching in Polymer Surface(Interface)Adsorption
"Polymer surface(interface)adsorption"is an important component of the polymer surface and interface chapter in Polymer Physics teaching.It is related to the preparation of polymer composite materials,colloid stability,wastewater treatment,life systems,and many other fields involving the adsorption of macromolecules on the surface(interface),with important theoretical and practical significance.In order to improve undergraduate students'understanding of the phenomenon of polymer surface(interface)adsorption,this article proposes to start from the single molecule level and display the two-dimensional diffusion motion of polymer single chains on the surface(interface)observed in scientific research.By introducing vivid examples,the"adsorption-diffusion-desorption"dynamic model is explained to help students clarify the molecular mechanism of the"polymer surface(interface)adsorption"process.It is essential for students to apply correct thinking in polymer physics to solve practical problems related to polymers by compensating for the lack of dynamic thinking in the learning process,highlighting the philosophical thinking of the movement of all things,and cultivating correct worldviews and methodologies.
