MATS8AG

Mechanical and  physical properties of polymers

ECTS Credits : 2

Duration : 21 hours

Semester : S8

Person(s) in charge:

Abdesselam DAHOUN, Professor, abdesselam.dahoun@mines-nancy.univ-lorraine.fr 

Keywords:

polymers, amorphous, semi-crystalline, polymerisation, properties, utilisation, forming

Prerequisites

Atomic and molecular arrangements: structures and defects, in service mechanical behaviour of materials

Objective:

Have a global overview on polymers, on their properties and utilisations

Programme and Contents:

The main structural and chemical features which influence the properties and the behaviour of polymers are: i) the nature of the monomer, ii) the architecture of the macromolecular chains, iii) the length of the chains and iv) the morphology at different scales. The objectives of this course are:

1. To analyse the functional groupings of polymers, reaction of polymerization and formation of the macromolecular chains,
2. To analyse the relation between macromolecular structures and the physical properties,
3. To understand the mechanisms that contribute to the physical and mechanical properties of polymers and describing the related laws in the context of sustainable development and material recycling
4. To study the relation between the formation and the macroscopic properties of polymers.

A. PHYSICAL & CHEMICAL ANALYSIS OF POLYMERS: - Principles and kinetics of polymerization - Macromolecular structure of polymers - Molecular weight distribution: Number-Average Molecular Weight & Weight-Average Molecular Weight - Physical & chemical characterization methods of polymers

B. PHYSICAL AND MECHANICAL PROPERTIES OF AMORPHOUS AND SEMI-CRYSTALLINE POLYMERS: - Glass transition and crystallization in polymers - Physical methods of micro structural characterization - Methods of mechanical characterization - Microscopic mechanisms of plastic deformation - Viscoelastic behaviour of polymers - Orientations and textures induced by forming processes - Viscosity and flow behaviour of polymers - The different forming processes of polymers
