“Mechanics of interpenetrated polymer networks”
Abstract:
We have been studying for a few years the mechanics of interpenetrated networks polymerized sequentially by swelling and polymerization steps. This strategy introduces a proportion of chains inside the material that are prestretched. When such materials are deformed the molecular strain becomes quite different from the macroscopic strain giving very interesting non-linear elastic properties and a 100 times higher fracture toughness. We will discuss how to optimize such properties and what are the molecular mechanisms leading to them.
