Elaboration et caractérisation de matériaux polymères poreux modèles à base d'émulsions contrôlées

Abstract : Polymer foams are cellular materials commonly used for safety applications in many industrial sectors (aeronautic, passive safety, gears...). To even improve their performances, the link between their structural parameters (cell sizes, density...) and their mechanical behaviour should be better understood and modelled. A way of producing such foams is to polymerize the continuous phase of highly concentrated emulsions. The advantage of such an emulsion-based strategy is that it becomes possible to take advantage of the good control over emulsion parameters (drop size, dispersed phase volume fraction, continuous phase composition) to elaborate model foams with cells and pores having narrow size distributions. The production of model foams makes it possible to determine independently the influence of each parameter on the compression modulus and to compare the results with existing models.
