Summary
Associative polymers and polymers in solutions: This course focuses on natural and synthetic hydrophilic and water-soluble polymers. It covers in detail the chemical structure of these polymers, their properties in solutions and their applications. First, the course presents the general information on water-soluble and hydrophilic polymers, from the point of view of their chemical composition, polymer-solvent interactions, and their behaviour in solutions (concept of conformation). The course then reviews different classes of natural polymers (polysaccharides and proteins), chemically modified natural polymers and synthetic polymers making up both classes of polyelectrolytes and polyamphiphiles. Students study the influence of the composition of these polymers (intrinsic parameters) and solution parameters (extrinsic) on their conformation and their consequences on the physico-chemical properties of the solution (viscosity, etc.). Finally, the course covers the study of hydrogels according to their formation mechanisms (chemical and physical hydrogels) and their characterisation using rheology. Different applications illustrate the courses in the cosmetics, food and biomedical sectors. Microencapsulation: This course presents through different applications the principle and the various processes of microencapsulation. Initially, the concept of microcapsule/microsphere is described, the interest of this technique and the possible release mechanisms of active agents. A review of the various microencapsulation processes used in industry is presented (interfacial polymerisation, coacervation, atomisation, etc.). The intrinsic parameters (associated with the composition [colloids, etc.] and the structure of the particle) and extrinsic parameters (dependent on external factors [temperature, humidity, pH, etc.] influencing the release kinetics are presented.
Educational goals
Associative polymers and polymers in solutions: Provide students with knowledge on the origin and chemical composition of the different types and classes of existing water-soluble and hydrophilic polymers. Thanks to this course, they will be able to predict the influence of parameters intrinsic to the polymer (its nature, molar mass, etc.), and those of extrinsic solution parameters (temperature, pH, salinity, etc.) on the physico-chemical properties of solutions and thereby understand their role within cosmetic compositions, food, paints, etc. The final part of the course, devoted to hydrogels, will give students knowledge of the mechanisms and parameters for the formation of chemical and physical hydrogels (reticulation, self-association, polyelectrolyte complexes, etc.) from uncharged polymers, polyelectrolytes, and amphiphilic polymers. The basic concepts of rheology seen in this chapter will allow students to characterise a sol-gel transition and quantify the viscoelastic parameters of hydrogels. Students will have the theoretical knowledge to address problems in which hydrophilic or water-soluble polymers could provide solutions for the formulation of cosmetics, food compositions, medical devices, etc. Microencapsulation: The aim of the course is to teach students the different processes for encapsulating active ingredients, and to be able to choose the one that would be most appropriate when faced with an issue that they might encounter in industry (pharmaceutical sector, food industry, etc.). The aim is also for students to be able to characterise the microparticles and choose the appropriate analytical techniques in order to control the effectiveness of the encapsulation process used, both in terms of the content of the active ingredient incorporated in the microparticle and in the release kinetics of the active ingredient.
