The instructor first describes typical higher order structure formation mechanisms that occur within polymer materials, and gives a detailed explanation of the structure formation principles based on thermodynamics. The instructor then explains the complicated higher order structures derived from multiple structure formation factors as well as structure formation mechanisms, all based on the newest research findings. Finally, students are introduced to examples of applying these higher order structure formations to property control of actual polymer materials.
Based on a variety of factors within polymer materials, a variety of higher order structures are formed, which control the properties and features of the material. By applying the various knowledge related to polymer science acquired up to this point, students gain an understanding of these structure formation principles, which is essential for basic research on polymer structure, and is useful in applied research that aims to create new polymer materials.
At the end of this course, students will get the knowledge about the various mechanisms of morphology formation in polymer systems. That is, they will be able to explain and/or understand
1) morphology formation mechanism of liquid-liquid phase separation (spinodal decomposition, nucleation & growth, and so on)
2) crystallization mechanism and crystalline morphology (lamellar structure, spherulite, and so on)
3) mechanisms of liquid crystallization and gelation
4) cooperative morphology formation by a combined effect of these factors
Morphology. Morphology Formation, Liquid-liquid Phase Separation, Crystallization, Cooperative Morphology Formation
