Obiettivi dell'insegnamento

The main goal of the course is to give the fundamentals of the materials used in electrical engineering applications; in particular, the course will focus on the three functional classes of materials classified in terms of their final applications: electronic conductors, electrical insulators and magnetic materials. Details on materials involved in some practical applications for common devices and alternative energy generators such as batteries, fuel cells, capacitors and piezoelectrics will be also provided. 


Risultati di apprendimento attesi

When the student has successfully passed the exam, he has a good knowledge of the following topics (DdD1):

  • knows the fundamentals properties of the three main classes of electrical materials, i.e. electrical conductors, electrical insulators and magnetic materials;
  • knows to which traditional class of materials they belong to, i.e. polymers, ceramics, metals and composites;
  • knows the relations existing between microscopic (physical-chemical) features of a material and its macroscopic properties and functions; 
  • knows the typical ranges of values of the qualifying electrical properties for each class of materials.

A consistent and continuous part of the course will be devoted to solve numerical and practical problems encountered in the application of electrical materials, then the student will be able to solve specific problems, and to select the optimal materials for any case (DdD2,3).

 


Argomenti trattati

1. Industrial and technological relevance of electrical materials and their classification.

2. Microstructure and bonding in electrical materials.

3. Dielectric materials: main properties, permittivity, electric dipoles, polarizability, mechanisms of polarization, behavior in AC and DC fields, applications and uses.

4. Polymers involved in insulators: differences among thermoplastic, thermosetting and elastomeric materials; glass transition, vulcanization, mechanical behavior.  

5. Electrical conductivity in metals: physical properties, drift mobility and drift velocity, conductivity and resistivity trends as a function of temperature and applications. Semi-conductors: physical-chemical properties, main materials, applications.

6. Magnetic materials: magnetic dipoles, classification of magnetic materials, domain theory; soft and hard magnetic materials: types and applications.

7. Piezoelectric materials: definition of direct and indirect effect, ferroelectric domains, hysteresis loop, PZT phase diagram, KNN properties, piezo-composites.

8. Examples of materials for alternative energy generators and storage devices: fuel cells, accumulators, capacitors.

Practical classes’ activity: numerical exercises on all topics of the course will be performed. All exercises and tests will be solved during class activity.


Obiettivi di sviluppo sostenibile - SDGs
Questo insegnamento contribuisce al raggiungimento dei seguenti Obiettivi di Sviluppo Sostenibile dell'Agenda ONU 2030:
  • SDG7 - AFFORDABLE AND CLEAN ENERGY
  • SDG11 - SUSTAINABLE CITIES AND COMMUNITIES

SDG7: materials involved in electrochemical devices for alternative energy production and storage (hydrogen-fed fuel cells, accumulators and capacitors), semiconductors for PV applications (10 h).

SDG11: materials for energy harvesting by exploiting innovative piezoelectric devices (6 h). 


Prerequisiti

It is required only a basic knowledge of chemistry and physics, in particular in terms of simple stoichiometric calculations, international system of units and physical phenomena. 


Modalità di valutazione

Written exam (2 h) with questions about theory and numerical exercises. It will consist of two parts: the first will be carried out by using MS Forms with multiple choice questions and open questions related to theoretical parts, the second one will consist in numerical exercises; students will be allowed to consult a formulary provided by the teacher.
