	Teaching Methods
	THE COURSE CONSISTS IN FRONT LESSONS (40H), CLASSROOM EXERCISES (10H) AND ACTIVITIES IN LAB (10H) FOR A TOTAL AMOUNT OF 60 HOURS WHICH ARE WORTH 6 CREDITS (CFU). IN THE LAB THE STUDENT WILL CARRY OUT EXPERIMENTAL MEASUREMENTS THAT WILL BE ANALYZED IN A REPORT TO BE DELIVERED AT THE END OF THE COURSE. ATTENDANCE AT LECTURES IS STRONGLY RECOMMENDED.

	Verification of learning
	AT THE END OF THE COURSE THE STUDENT HAS TO TAKE AN ORAL EXAM AND A DISCUSSION OF THE REPORT THAT HE WILL PREPARE BASED ON THE EXPERIMENTAL DATA COLLECTED DURING THE LABORATORY EXPERIENCE. THE ORAL TEST CONSISTS OF AN INTERVIEW WITH QUESTIONS AND DISCUSSION ON THE THEORETICAL AND METHODOLOGICAL CONTENT OF THE SUBJECTS OF THE PROGRAM AND IT AIMS TO ASCERTAIN THE STUDENT'S LOGICAL-DEDUCTIVE AND SYNTHESIS SKILLS AS WELL AS THE ABILITY TO DISCUSS THE VARIOUS PROPOSED THEMES WITH THE APPROPRIATE TERMINOLOGY. THE STUDENT WILL PASS THE EXAM WITH THE MINIMUM THRESHOLD IF HE DEMONSTRATES KNOWLEDGE OF THE DIFFERENT NANOPARTICLES AND POLYMER NANOCOMPOSITES, IF HE IS ABLE TO DEFINE THE VISCOELASTIC, MECHANICAL AND ELECTRICAL PROPERTIES OF THE NANOCOMPOSITE SYSTEMS AND IF HE HAS SET THE RESOLUTION OF THE EXPERIMENTAL DATA ANALYSIS REQUIRED IN THE REPORT. EXAMINATION IS UNDERSTOOD TO BE EXCELLENT IF THE STUDENT HAS EXHAUSTIVELY DISCUSSED THE NANOFILLERS, THE PREPARATION AND PROPERTIES OF NANOCOMPOSITES, AND THE CONCEPTS OF VISCOELASTICITY AND IF HE HAS RIGOROUSLY ANALYZED THE EXPERIMENTAL DATA IN THE REPORT. THE FINAL MARK IS ABOUT 70% OF THE ORAL MARK AND ABOUT 30% OF THE EVALUATION AND DISCUSSION OF THE REPORT.
