Course description and aims

Gels are important soft-materials.
This course focuses on the crosslinking of polymers, which is an important method to synthesize gel, and on the properties of gels. Topics include crosslinking between polymer and low molecular compounds, polymer and polymer, direct synthetic reactions of gel from monomers, Flory's gelation theory Carothers equation, the properties of gels and thermodynamics of swelling of gels. The course enables students to understand and design of crosslinking for gels.

Student learning outcomes

By the end of this course, students will be able to:
1) Explain the principles of crosslinking of polymer.
2) Understand the properties of gels synthesized via crosslinking.
3) Acquire the relationship between crosslinking and properties of gel.
4) Obtain gel point and design the crosslinking system for certain gel.

Keywords

Crosslinking, gel, gel point, polymer complex, swelling.

Competencies that will be developed

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

Class flow

Towards the end of class, students are given exercise problems related to what is taught on that day to solve.
Before coming to class, students should read the course schedule and check what topics will be covered.
