Syllabus

Course overview and goals

The properties of polymer solids, such as fibers and films, are governed not only by the chemical structure of polymer chains but also by higher-order structures arising from chain aggregation, including crystalline and amorphous structures as well as molecular and crystalline orientations. This course examines crystalline, amorphous, liquid-crystalline, and microphase-separated structures in polymer solids, emphasizing their formation mechanisms, characterization methods, and relationships to material properties.
The aim of this course is to provide students with an understanding of the higher-order structures of polymer solids and their formation mechanisms, and to develop the ability to explain and evaluate the properties of polymer materials based on their underlying structures.

Course description and aims

Upon successful completion of this course, students will be able to:
1) Explain the characteristics of crystalline, amorphous, liquid-crystalline, and microphase-separated structures found in polymer solids.
2) Explain the structures, crystallization mechanisms, and crystal morphologies of crystalline polymers.
3) Explain thermal transitions in polymer solids, including crystal melting and the glass transition.
4) Explain structure-property correlations in polymer solids.
5) Explain the formation principles of self-organized structures in liquid-crystalline polymers and block copolymers.
6) Explain the principles and characteristics of analytical methods used to characterize polymer structures and thermal transitions.
