Course Syllabus

Electrical properties of polymers represent an important part of polymer condensed matter physics.  They can be divided into two major parts: insulating and semiconducting/conducting properties.  In this short course, we will primarily focus on the insulating properties in close relationship to polymer structures in the solid state.  In the first part, crystalline structures of polymers are introduced, including X-ray determination of crystal structures and chain conformations.  In the second part, dielectric polymers are introduced, where four types of polarization exist.  They include electronic, atomic (or vibrational), orientational (or dipolar), and space charge (including both ions and electrons/holes) polarizations.  The electrical behavior of dielectric polymers can range from linear dielectrics to nonlinear ferroelectrics, and numerous practical applications can be found for cable insulations, capacitors, electrets, and actuators.
