The primary objective of this course is to equip students with the competence to establish the **structure-property relationship** linking the chemical structure, molecular architecture, and morphological properties of polymeric materials. The course content details polymerization mechanisms, the formation of amorphous and crystalline phases, the analysis of thermal behaviors such as glass transition and melting, and the interpretation of mechanical strength tests. Furthermore, by examining the characteristics of various material classes—ranging from thermoplastics to thermosets, elastomers, and dendritic structures—the course aims to provide the necessary theoretical and technical foundation for making appropriate material selections in engineering designs based on performance criteria (e.g., specific stiffness, strength).

This course serves as a comprehensive introduction covering the fundamentals of polymer science and technology. The content begins with the historical development of polymers, their classification (thermoplastics, thermosets, elastomers), and the examination of fundamental polymerization mechanisms (addition and condensation). The chemical structure, atomic bonding forces, and molecular architecture of polymeric materials, along with their effects on solubility and electrical properties, are analyzed. Subsequently, the course details polymer morphology, the formation of amorphous and crystalline regions, and the roles of thermal transitions such as glass transition and melting temperatures on material processability and physical behavior. Within the scope of material characterization, mechanical testing methods such as stress-strain (tensile), impact strength, and viscoelastic behavior, as well as fracture mechanisms, are covered. Additionally, cross-linked structures (epoxy curing, rubber elasticity) and special polymeric systems like hydrogels and dendrimers are introduced. Finally, optimal material selection processes in engineering design are taught using material selection charts and performance indices (e.g., specific stiffness).
