PHYSISCAL CHEMISTRY OF SOLID STATE AND NANOSTRUCTURED MATERIALS

Course objectives

In accordance to the first two Dublin descriptors, at the end of the course the student will have understood the following concepts: a) meaning of conducting polymer and doping phenomena in semiconducting polymers; b) principles of synthesis and characterization of conducting polymers; c) materials science at the basis of the choice of specific polymers as active materials of devices for electrochemistry, optics, electronics and sensors The student will use the concepts grasped during the course of Physical Chemistry of the Solid State and Nanostructured Materials to prepare and characterize polymeric materials with different properties of electrical conduction. The course has also the finality of developing the communication skills of the student (fourth Dublin descriptor). This is realized through questions during classes and in the final exam.

Prerequisites
Knowledge of general chemistry, physical chemistry, mathematics and electromagnetism
Books
- Handbook of conducting polymers, voll. 1 and 2 (editor: Terje A. Skotheim), Wiley - First edition (1986) - Solid state chemistry and its applications (Anthony R. West), Wiley - Second edition (2014) - Slides of the lectures
Teaching mode
The course of Physical Chemistry of the Solid State and Nanostructured Materials is taught through the explanation of the various topics that are presented in PowerPoint slides
Frequency
The course of Pjhysical Chemistry of the Solid State and Nanostructured Materials is offered within one semester. The frequency is two lessons per week. Every lesson has a duration of two hours.
Exam mode
The student is evaluated through a written exam. The exam consists in the explanation of the concepts presented during the course and calculations based on the formulas of the course. In doing so, the student uses only pen and paper. The exam lasts 3 hours. The number of questions is three. It is strictly forbidden the use of computer, laptop, textbooks, smartphones, notes and slides of the course. The student has to indicate his/her name on each sheet of the test.
