Natural polymers are playing a key role in the frame for bioeconomy. They could replace fossil-based polymers and make a positive contribution to the mitigation of climate change and the sustainable use of natural resources. This will require a better understanding of how the structure and functionality of the materials interrelate. In this context, this course relates with key topics on:

1. The biomass valorization and natural polymers, including their origin, extraction/isolation, characterization, and physiochemical, structural, mechanical and their biological properties;
2. The development of novel multifunctional bio-based materials architectures and manufacturing processes is also assessed, as well as, their applications in key areas such as biomedicine, composites, agriculture, and environmental engineering are also discussed.

Students acquire the competence to think of biomass valorization and biopolymers as a sustainable alternative to fossil-based polymers for the development of polymeric materials and composites. Basic knowledge in polymer chemistry is beneficial but not necessary. The course content will include a series of lectures using Power Point slides, case studies, exercises and in-class oral presentations by the students. Students should keep up with assigned reading and ask questions in class or by email.

L’objectif de cette UE est d’une part la maîtrise des bases élémentaires de la thermodynamique des surfaces et d’autre part la bonne connaissance des différentes familles d’adhésifs. Nous abordons la thermodynamique des surfaces par les notions de mouillage et d’énergie de surface. Une description des adhésifs à mise en œuvre chimique ou physique et des auto-adhésifs est proposée avec des exemples d’applications dédiées. La formulation des adhésifs est exposée par la description des composants d’un auto-adhésif, leur mise en œuvre pour des applications prises comme exemples modèles, les règles scientifiques et empiriques de formulations (gestion de la viscosité, de l’élasticité, de la cristallinité, de la transition vitreuse, …), la mesure/prédiction des propriétés d’adhérence et enfin les règles générales qui dominent aux choix des adhésifs. La mesure des propriétés d’adhésion sera exposée par les différentes techniques existantes.

The objective of this course is on the one hand to master the elementary basics of surface thermodynamics and on the other hand to have a good knowledge of the different families of adhesives. We approach the thermodynamics of surfaces through the notions of wetting and surface energy. A description of chemical or physical adhesives as well as pressure sensitive adhesives is proposed with examples of dedicated applications. The formulation of adhesives is presented by describing the components of a pressure sensitive adhesive, their implementation for applications taken as model examples, the scientific and empirical rules of formulation (management of viscosity, elasticity, crystallinity, glass transition, ...), the measurement/prediction of adhesion properties and finally the general rules that dominate the choice of adhesives. The measurement of adhesion properties will be presented by the different existing techniques.

The main objective of this lecture is to train students to make the link between the knowledge, as they learned during the first year of the master, on synthetic polymer and materials thereof and biomacromolecules. The format is hybrid, between lectures and student-based learning through literature studies and oral presentations in groups. The main topics are dedicated to the relation between structure and function and to the self-assembly of polymers and biomacromolecules in dilute aqueous solutions.

A part of the course presents the specificity of amphiphilic copolymers and their specific self-assembly behavior in water. The properties of these amphiphilic copolymers in water are presented in relation to the diversity of industrial applications offered by these materials. After an introduction to the different classes of amphiphilic copolymers (topologies, microstructure, natural or synthetic polymers, stimulables), the challenges associated with their characterization and processing will be discussed in relationship with the targeted properties related to applications.

Structure du cours :

The lecture will be divided as follows

Industrial applications of amphiphilic copolymers

1. Definition and library of structures of amphiphilic copolymers based on natural or synthetic copolymers
2. Tools to tune the amphiphilic behavior
3. Challenges of production and characterization of amphiphilic copolymers
4. Roles and specifications of amphiphilic copolymers for diverses applications: rheology modifiers, thickeners, hydrogels, emulsifier, dispersant, colloidal particules.

The properties will be discussed in relation to various industrial sectors: building, paints, cosmetics, biomedical, filtration membranes, agri-food…

The objective of this course is to establish a state of the art of polymer-based nanocomposites. After defining nanocomposites, we review the main processing methods for these materials, focusing on the specific issues and challenges they raise. We then study the specific properties of nanocomposites, with a particular focus on their relationship with the nanoscale of the fillers. We end up with studying several applications.

The teaching strategies of this course include traditional course and several case studies.

Course description:  The objective is to introduce to students organic and hybrid (organic-inorganic) materials presenting a nanometer-scale structure such as nanocomposites & block copolymers. We will see that nano-structuration can induce or accentuated properties compared to usual materials.

Course structure: During the lectures a presentation will be given on :

1. Introduction to the nanoWORLD !

2. Observe, manipulate and characterize at the nanoscale

3. Organic nanomaterials and their applications

Nanocomposites & Block copolymers for nanolithography, ion diffusion in battery & fuel cell, etc. (based on published papers)

The course will be supplemented by TD sessions during which specific scientific papers will be discussed. Finally, at the end of the semester, the students will have to prepare and present a presentation on a chosen topic based on nanomaterials.
