OVERVIEW

The teaching provides practical tools to develop knowledge on laboratory methods for the synthesis and characterization of polymeric materials of significant industrial interest.

AIMS AND CONTENT

LEARNING OUTCOMES

The aim of the course is to give knowledges about the polymerization methods and the characterization of polymer materials.

AIMS AND LEARNING OUTCOMES

Attendance and active participation in the proposed training activities and the individual study will allow the student to:

- know in depth the main polymerization techniques and be able to experimentally carry out some syntheses;

- identify and know how to use the main types of polymer characterization techniques;

- understand the potentiality and the limits of the methods of instrumental characterization;

- acquire a correct scientific terminology for the study of macromolecular chemistry.

TEACHING METHODS

Lectures in order to prepare the lab and frequency of the laboratory. Copies of slides presented in class will be available on AulaWeb and can be used as a basis for the study. The slides can only be a reference for the study of the topics, to be added to the frequency of the lessons or the study of texts. These slides will help in the drafting of the reports to be presented which will be linked to the laboratory activities. The attendance of laboratory, and preparatory lectures for the practical activities, is mandatory.

 

SYLLABUS/CONTENT

Synthesis of polymers in bulk and emulsion will be developed, after purification of monomers and initiator with different methods. Correlation between synthetic parameters as monomer and initiator concentration etc. with molecular weight and yield of polymers will be carried out.

The results will be discussed by the students, comparing data obtained with different synthesis conditions. This experience will allow students to apply some fundamental concepts analyzed in some theoretical courses dealing with macromolecular chemistry.   

Polymers will be fractionated and characterized by viscosimetric (with Ubbelohde viscosimeter), thermal (DSC) and spectroscopic measurements (FT-IR with ATR and DRIFT). Study of mixing of polymers will be performed, by thermal analysis and by using of empirical equations. Measurement of superficial properties of polymeric films, by determination of contact angle will be carried out.

The experiments carried out in the laboratory will end with a discussion on the results and with the description of the report, that will be discussed during the examination.

EXAM DESCRIPTION

The final evaluation will be considered the following weights for the various examination parts: 30% for the oral examination, 30% for the laboratory skills and 40% for the laboratory reports.

The oral examination is conducted by two professors. They will verify the achievement of the learning outcomes and when these are not met, the student is invited to extend the study. To ensure uniformity between the examination topics and those actually carried out during the course, a detailed program is illustrated in the AulaWeb page, so that students themselves can verify adherence.

In case of emergency and only according to specific indications by the University of Genoa, the assessment method for the exam might be changed, including the possibility of an online procedure.

 

ASSESSMENT METHODS

Details on how to prepare for the exam and the degree of depth of each topic will be given during the lessons.

Both through the reports of the laboratory experiences and through the oral examination, the student's ability to discuss critically on the course topics, to elaborate the concepts presented in class and to integrate the information coming from the various topics by a personal study will be assessed. The ability to illustrate in detail the main polymer synthesis techniques and to apply the characterization techniques, showing their potentiality and limits, and demonstrating ability to interpret, compare and discuss the results obtained, in a clear way and with a correct scientific terminology will be evaluated; the quality of the oral presentation will be considered.
