Application of atomic force microscope in polymer experiments teaching |
| |
| Abstract: | Atomic force microscope is used to characterize the surface structure and morphology of the samples. It is easy to operate and the resolution can reach nanometer level. Atomic force microscope is one of the important tools for the analysis of materials and the research of nanotechnology. Four experiments were taken as examples, including the branched structure of polymer, the microphase separation structure of polyurethane, the crystallization and melting behavior of polymer and the preparation of high density polyethylene ( HDPE) microporous membranes by stretching HDPE casting films uniaxially. Atomic force microscope is applied to polymer physics experiments teaching in order to better clarify the intrinsic relationship between polymer structure and properties, and make the students deepen the understanding of the basic concept and theory of polymer physics and improve their ability to analyze and solve problems. |
