Course Description

Polymer physics is about the physical properties of a polymer and polymeric materials. Polymer physics, together with polymer chemistry, constitutes polymer science. It also plays a significant role in the development of polymer engineering. It is the fundamental knowledge required for anyone who is to be engaged in polymer industry. This course presents the mechanical, electrical, and optical, etc., properties of polymers with respect to the underlying physics and physical chemistry of polymers in solution, melt, and solid state. Topics include thermodynamics of polymer solutions, blends, crystallization; molar mass, chain dimensions, conformation and morphology of polymer chains in solutions, melts, blends, and block copolymers; an examination of the structure of glassy, crystalline, and rubbery elastic states of polymers; liquid crystallinity, microphase separation. Case studies include relationships between structure and property in technologically important polymeric materials.
