Course description and aims

This course focused on the basic concept of multi-component polymer system (polymer alloys), especially, the phase behavior, thermodynamics, phase separation behavior, morphology control and interface in polymer alloys are explained.
Mixing different polymers is carried out widely to satisfy some requirements. So the polymer alloys are used as practical use materials widely. It is desirable to understand the basic of the essence of polymer alloys and importance of structure design.

Student learning outcomes

By the end of this course, students will be able to understand:
1)Wide applications of polymer alloys as practical use materials
2)Basic concept of thermodynamics of phase diagram, structure-properties relationship, and control of phase-separated morphology in polymer alloys
3)How does the physical chemistry that students learned as basic knowledge of materials help the concept of this material?

Course taught by instructors with work experience

Applicable How instructors' work experience benefits the course
Multi-component polymeric materials (polymer alloys) are often used as practical materials. As the basis of the mixed material, material design such as the structure formation mechanism and structure control methods that affect the physical properties learned in this lecture is particularly important and can be applied to material development.


Polymer alloys, Polymer blends, Phase diagram, Free energy of mixing(Flory-Huggins equation), Control of phase separated morphology, Spinodal decomposition, Nucleation and growth, Reaction induced phase separation

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

Based on uniquely created learning materials, discussion is held with questions thrown in. At the beginning of every lecture, the answers of the quiz from the previous class are explained, and in the latter half students will do a quiz related to that day's lesson.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
